Firstly, I would like to apologize for my bad vocabulary since I'm not a native English speaker.
Let me explain my story in as many details as I can for better understanding the issue
I am a 27 year virgin old male who has been officially diagnosed with borderline personality disorder last year while getting treatment at a psychiatric hospital (period from July-August 2013th). During that time I met a 24 year old girl which I instantly fell in love with since she was very attractive and cute in my eyes. Later on I found out she also has BPD diagnosis aswell. At first she was very cold and aggressive towards me and hardly wanted to exchange any words because she considered me as an enemy and a person which brings bad luck to her. She didn't had any logical reason for that kind of behavior since I was nothing but an angel towards her. It took almost 3 months for her to accept me as a friend only because of my enormous persistency. When we got dismissed from the hospital we lost contact for some time since she went to her mom's place. Anyways we met numerous times in town and chatted a lot. Slowly but steadily she started opening up and told me everything about her life and childhood. She said that the first BPD symptoms showed up while she was 15 and that she lost virginity with a guy who is 12 years older than her which abused her (ie. physical violence and drugs). Also she has a child (3 year old girl) with that guy, but can't see her very often since she lost custody in court over her. Her father died while she was 5 and doesn't have any relatives except her mom who can't take proper care of her because of poor financial situation.
Couple of months ago (period from April-July 2014th) I lost complete contact with her (her cellphone was switched off and wasn't active on Facebook at all) that was a soul breaking experience for me and I was feeling completely depressed since I was afraid something bad happened to her. The reason for my concern is that I know for a fact she likes to hang out with any guy she finds (whether over FB or in real life) and has unprotected sex with them (I was on the blacklist in her brain nothing more but a naive pleasing friend). I was waiting, waiting and waiting logging into my FB account couple of times every day during those 3 months and waiting like a maniac to see whether she will receive (ie. marked as seen) any of my messages. Luck smiled back to me when I have seen that she received my messages (somewhere at the end of July). She didn't reply to any of my messages for about a week although I was 100 percent sure she has seen them. Finally, she messaged me back after a week and told me that she is at her mom's place without giving me any answers where she was during all that time (that pissed me off because I cared for her and she treated me like trash).
I insisted we meet somewhere in town for a coffee, but she was avoiding to meet-up antagonising me even further. My persistence paid off again and we finally met. When I saw her I couldn't recognize her at first because her physical appearance changed (she changed her hair style and I noticed that she gained a few pounds). I was also surprised that her communication skills improved and was a lot calmer than ever before (like a completely changed person). She told me that her mom placed her at a drug rehab clinic and that she had restricted communication with the outside world from there. I asked her how was it there and she said she needed to go there for her own well-being, but also confessed that it was very difficult because she didn't had her freedom and had to various chores (like washing clothes, taking care of animals and cutting the grass). I was still trapped in friend zone status at that time, but was also relieved a little knowing that she didn't meet with any other guy except me when she returned from rehab clinic (she got antisocial briefly). She was normal for 1 month and then she exploded again and regressed to her former lifestyle (taking various pills/drugs and having sex with strangers). At that moment I raised a white surrender flag and lost all hope that we will ever be together as a couple and stopped calling her and sending her messages via FB. One day she called me in a crying voice that her mother kicked her out and that she has nowhere else to go and I offered her help to come at my place. We had normal friendly communication for 13 days when she snapped for no reason and went to some guy and turned off her phone for 3 days (logically she was having sex with him). When she returned to my place I sent her back to psychiatric hospital and stopped talking to her. That was her 7th hospitalization later I found out. She contacted me via FB couple of days ago and said she will be my GF (finally yeah after 1 year of trying i thought) and have sex with me, but I will have to be obedient and fulfill every demand she wants. Yesterday, she got released from hospital (after approx. 2 weeks) and I went with her to pickup 2 stray puppies (her wish). Today, I managed to convince her to have sex with me and she accepted, but that lasted only couple of seconds since I was inexperienced (never had sex before in my life). After that event she went cold called me a "friend" and broke my heart.
Thats all. Do you have any suggestion/idea what I should do now? I never felt so bad in my life as today.



And now back to the present time today
