I will try to tell the whole story, as I am at a loss right now about what to do.
I have a girlfriend (I am a woman too) we have known each other for about 7-8 months, we've been dating for 4 months now. I think she has a lying addiction.
We live in different cities not really far from each other, it takes only 20-30 minutes by car to meet, but we can't really see each other. She lives with her parents (she has a sick sister, I know that for a fact, and it is quite a burden for all of them, and so she claims she can't leave them because she has to be there for her sister), she works there. First we had different schedules as well as I'd been working in the afternoons and she has her shifts in the morning, so it was really hard to find time to spend together but we managed. She even found the time to surprise me a few times, she just turned up on my doorstep without a word. But after a month or so problems started to rise. I found a different job with more money and started to work there, I didn't have to work in the afternoons so I thought that finally we got to see each other more. It was all well and good for about two or three weeks, when one morning she announced that she couldn't get up from bed because her back hurt. I believed it because she told me on several occasions that she had had back problems, but that afternoon when she went to a doctor she told me she needed surgery. It was the worst three weeks of my life, as I couldn't even visit her in the hospital because she didn't want me to meet her parents. They know she is a lesbian and she says they hate her for it (I never really understood why she lives with them if this is the case).
While she's been in the hospital I found out that she and her ex were to see a movie on a day when my girlfriend told me a totally different story. It totally broke me that she lied to me. I knew they were good friends after the breakup, I even encouraged her to meet and talk to her, because she doesn't really have so many friends and I know she's still very important to her. When I told my girlfriend I knew about the movie she denied everything, but after I told her the name of the movie she confessed. We had a talk, I asked some time to think, while she was practically begging me not to leave her. I gave her another chance, but after that one lie came after another. She told me she went to sleep, and half an hour later she came across me in a bar with some random people. She told me she was working on Halloween, but one of my friend's girlfriend were parting exactly where she was and I had to find out from her pictures on facebook that my girlfriend was there too. She had no reason to lie to me, as on that night I couldn't even meet with her. Several occasions she just can't remember what she said to. For example she says she goes to work and an hour or so later she texts me that she's enjoying herself in a spa...
At the end of december I had enough and called her on one of her lies. She totally broke down, she told me she knows she has issues and that she wants to change and that she feels she is loosing herself. She asked some time to spend alone, she claimed she didn't even go to work for a few days. We rarely talked, just a few texts a day, and it was always her who initiated the conversation as I really wanted to give her some space and time. (I think sometimes I was a too much for her. I always texted her, constantly wanted to talk to her, I somehow suffocated her but we had a big talk about it and then I took a few steps back.)
But I got really suspicious that it is not simply a personality issue with her but something more serious. After our two week break she claimed that she wanted to go to therapy and wanted some help but I'm afraid it is just another lie. She keeps lying to me about minor things.
Last week I asked her to show me her scar from the surgery but she refused to take off the bandage. She said it was bleeding, though two days earlier she was at the spa again. I asked her if she had surgery at all, then she got really upset with me but when I remained calm and told her that I still love her she should just be honest with me, she remained totally silent.
I do not even know that she cheated on me or not (probably, as I know for a fact she befriended a few girls on facebook during our relationship from different chat rooms and dating sites, but when I asked about them she told me they were just talking but when we met on that night in the bar she was with one of them.)
She says she knows she is not reliable and asked me not to love her and just leave her because she wants to spare the heartache for me because she can't change. I think she doesn't even love me and this is just an excuse so it is not her who breaks the whole thing off.
Now I really don't know what to do.
I don't want to leave her behind but I obviously cannot be in a relationship with her either. I want to help her to get some help I just don't know how to do it. I don't want to scare her away but I want her to know that it is not OK to lie to me either. I don't know how to do it without hurting her even more. I just don't know what to do. Some advice? I would appreciate it.
