Do I have delusional jealousy?

Hi
I'd like to share my experience. My husband and I have been having a very difficult time and we think that I might have delusional jealousy. I don't mean to post this to hurt anyone or asking for your sympathy but I'd like to let you know my story and I'd be grateful to have your comments. You might think all that you're about to read is all made up and only exist in my head but these things have actually happened and we think it might have had made my normal jealousy into a delusional one. It started 18 months ago when my husband quit his job in England and moved us back to Thailand with our fist child she was one year old then. I didn't really want to move back as we've been living in England for several years and have made lots of good friends but we thought it would be a good opportunity for our daughter to have more outdoor life and to see our family and friends as we used to live there sometime ago. My husband was waiting to start a new job in Singapore and the first couple of months he went out for drinks with his friends at least once or twice every week.I didn't really like him staying out late (from 10pm till 3-4am) with his friends and that is when I started becoming suspicious of my husband and accusing him of seeing another girl. About a year ago just a month after him starting his job in Singapore which he had to fly there every week and stay sometimes at his male colleague or a hotel near his office from Monday till Friday and then he would fly back to Thailand to spend time at the weekend with us (I'm just a stay at home mum and live with our daughter in Thailand and I don't go out because it's difficult to get babysitting here so I stay home with the baby and he can go to the social gatherings), he came back to Thailand to spend time with us for the weekend, on a Saturday night, he went out for drinks with his friends and he came home at 6am very drunk and just went straight to bed. I'd been up all night waiting for him as he called about 2am telling me that he's coming home now. At 5am I was worried about him so I called his mobile but it was off and then he returned home at 6am. I found a box of condoms which has not been opened I then asked him why he had that in his pocket which he replied he hasn't done anything. I looked in his phone and found a girl's number on his phone and in his wallet. I couldn't sleep all night with thoughts going through my mind. He said they gave out condoms to everyone at the bar that he went to his friends and he put his mobile on the table and a girl that work there saw photo of our daughter so she asked him if she could have a look at more photos in his phone and she must put her number on his mobile. I asked him about the number for the same girl in his wallet he explained that this girl looks like she fancy him and might have slip her number in with the change when he paid the bill he was so drunk he didn't really check but he swore that he didn't do anything with her. He then threw the box of condoms away. Two nights later he went out to watch a game of football in a bar with his friends. He came quite early with a bright pink lipstick mark on the back of his shoulder. He said he doesn't know how it can get there but the bar was pack full of people watching the game so someone could have walk right into him. He still had that girls phone number on his mobile so I decided to call. She picked up and I asked her all the questions I need to know. I didn't tell her what my husband look like but she could give me a perfect description of what he was wearing on both nights and she could even describe the photo of our daughter on his mobile but she confirmed that he never had sex with her. I was devastated to hear that I honestly couldn't tell who was telling me the truth. Next morning I told him exactly what I had found out from that mysterious girl. He denied that he knew her or even fancy her or was tempted by her. He called her number in front of me and put on the speaker phone. He asked her how did he know her and why he had her number she didn't say anything and just hang up. He then deleted her number and threw away her number that was in his wallet. Since then we had numerous arguments and I didn't know who to believe part of me believe in his explanation that it is just a trick that a bar girl here would do to get a man if they can cause them to split up and part of me didn't believe it and thought that he is quite an attractive looking man so this girl came on to him and he might have been flirting with her or even tempted by her but realized at last that it was wrong...well I guess I would never find out. Since then my husband didn't go out that much and spent more time with us like taking us to the zoo, the beach, playing with our daughter more but my suspicious is still lurking in the back of my head. Things got bad on his birthday last year after I took him out for dinner and accidentally bump into a group of his friends at the restaurant. They asked him to go out with them for his birthday later that night and he told me he want to go out and celebrate with them. When we got home he was busy checking his facebook message and texting his friends we then had massive argument because I didn't want him to go out as I thought they might go to his friends bars and there might be girls coming up to kiss him for a birthday present. My mind was going through so many terrible thoughts and I was so worried that something will happen. He ended up staying at home with us that night and when I looked back at this I felt terribly awful. I was petrified of what could happen and how I would handle it. My husband and I have been together for nearly 10 years and he has never once cheated on me but my paranoia just keep growing. The next day he took me to see a psychiatrist. My husband didn't think that I might have delusional jealousy but he thought I might have post-par tum depression or separation anxiety. Anyway, I had been to see psychiatrist for 2 months and he gave me prosac to start with and then switched me to lexapro which I was allergic to. By then, I had been doing online CBT programme which help me to get better. We also went to see a marriage counsellor but we only went there once as my husband disagree on the things the counsellor said and we were moving to live in Singapore together so we stop seeing the counsellor and the psychiatrist signed me off as I was mental recovered from depression. Once we were in Singapore things were ok until one afternoon I was borrowing my husband laptop to work on my CBT session, a skype message of his female colleague popped up about what people in their office should be wearing to the Christmas dinner and she wrote to my husband ''I think you would good in red'' and that set my suspicious mind running mad. During that week the executive director of his company whom he knows for15 years came to the annual meeting in Singapore so he told me that there would be 2-3 nights that week that he will be home late. One night about 1am in the morning he hadn't text my mobile to let me know when he was going to be back I started worrying about the skype message that I saw the other day between him and his female colleague and I decided to call him. It took him a while to call me back I was really worried by that point. He said he was having drinks with his boss and his clients. I asked him if that female colleague was there and he said know and he confirmed that she was just a secretary. When he came back we had arguments about I'm not trusting and think that he might be out seeing his colleague which I found out later was nothing like I was worrying about. It was so embarrassing for him as he was out with his boss and his clients and they probably overheard the conversation. I felt terrible for doubting him. He was so stress at work so he decided to leave his job and we've moved back to Thailand in February 2012. He told me that the only way we could live together happily and keep our family together is to trust each other. For the past 18 months it has been a roller coaster ride for us and it feels like we're living in our nightmare. Since we've moved back to Thailand he hasn't been out alone with his friends for drink at all until April. This month he has been out every week at least 1-2 nights a week and I don't really like the late night drinking out in the town here. There so many bars with girls wearing next to nothing waiting to be pick up. It was all ok until last Saturday when he came back after out drinking with friends that I found a parking ticket of a hotel in the town on that night in his wallet. I asked him what it was and why he was there and that started of the arguments again. He said it was just a parking ticket where he parked the car that's all. I love my husband so much and I care about him but all these doubts and arguments have made us apart. I'm worried that we will split up when we moved back to Thailand just like many of our close friends because the husbands have found new loves. I know that my husband loves me and cares about and would not do anything to break us up but sometimes when he is out till late at night I start to worry and I have doubts in my mind. I tried not to think about it or believe it but sometimes is so hard to do. It's killing me...I used to be happy and never worried or having doubts about us. I feel like what I'm doing is hurting him and pushing him away and destroying a perfectly good marriage. I went to see a psychiatrist the day after we had our recent arguments. My husband and I thought that I have delusional jealousy but the psychiatrist disagreed and thought that I have depression and anxiety disorder. We also noticed that recently I feel quite depressed, unloved, anxious around my period so we suspected that I might also have PMDD. The psychiatrist gave me xanax, zoloft, lorezene and desirel to take daily. We thought that was quite a lot of drugs to take daily so I've just started taking only zoloft in the day and xanax in the night to help me to sleep. I want to get help I want us to be the same way we used to be. It's torturing not only for him but for me too and I want it to go away. I told my husband that I don't want to hurt his feeling any more so it is up to him what he decided to do. I hate the person that I've became and I want to get well and live happily together again not only for me but for my daughter. She's 2 years and 4 months old and adores her dad and I want to keep my family together. Do I have delusional jealousy? Will I be fully recovered from it? Will I turn psychosis forever? Please help and thank you.

It doesn't really sound like DD to me. But Im new to all this. From what I've read though you do not sound like DD at all.
