Ok here's my situation. In may I met a girl who I really liked, HB9. We had amazing chemistry and spent an amazing night together. Then we met up again and had an amazing day together. I needed to go away to do my last contracted working on a ship and she said she would wait for me.
She told me it was love at first sight, I am really special and she likes me so much. She was sending me really sweet messages and calling me every night and saying she didn't want anyone else.
About a month into my contract she starts getting more and more distant until I realised it was always me calling her and initiating IM convos and texts, then when she replied her answers were short and un affectionate. Then when I came home she made no effort to see me and kept flaking when we arranged it.
So we finally arranged to meet again on Sunday, but on Saturday I saw a really suspicious fb thread between her and another girl (this is a lesbian relationship btw.) My gf's fb status was 'doing CPR training today' and this girl had commented 'you can do mouth to mouth on me anytime

' and my gf had put 'yeah you can be my model patient you crazy girl', the girl replied 'you like this crazy girl

'
So I was like wtf. I sent my gf a message saying 'who's Cynthia? why does she want you to do mouth to mouth on her?' and my gf was like 'she was joking, you're so immature. Just because you've been cheated on before doesn't mean everyone is the same. Good luck, not everyone is the same.'
So I left it a day and sent her a message saying 'I'm not immature, I've had more life experience than anyone I know.' And she just replied 'I can't talk now, I'm busy.' That was on Sunday and we haven't spoken since...
She is always online but hasn't tried to talk to me. Even worse she has blocked me from seeing her facebook wall and has re opened her account on the dating site we met on.
What's the best way to proceed now? Do you think she was cheating on me the whole time or was I being paranoid? I want her back because she is gorgeous and I really like her, but I know if I chase her it will push her away. It's killing me though that she is looking for another gf on a dating website.
I know you will say move on etc but she liked me so much when we met, there must be a way to get that back?
