I met my ex about 5 months after splitting up with a long term partner. Everything was fine between us until my ex partner (long term) found out I was seeing someone else and started to try to win me back, letters texts etc.. This went on for few months and made me really think about who and what I wanted. I decided to stay with my now ex girlfriend. Around christmas time last year we were having lots of arguments (caused by my ex long term partner) after a drunken night out I ended up sleeping with my ex long term partner. This is the first time in my life I have ever done anything ike that and felt so guilty after. Anyway my ex long term partner went straight round and told my now ex girlfriend and we split up for about a month until I could convince my now ex girlfriend that it was her I wanted to be with and I made a stupid mistake. I changed my mobile number and started afresh with my now ex. After a while my ex long term girlfriend got back in touch and tried to apologize she was really upset and we started texting each other (just about random stuff) my now ex found out about this and said she would end things between us I I didn't change my mobile number again, but I promised her that if she ever got in touch again I would tell my now ex girlfriend and change my number. Around 4 weeks ago now she did text me again saying that she was really ill and needed to go into hospital - me being stupid replied to her text and did not tell my now ex girlfriend about it, she did not reply to my text asking how she was so I ended up going round to her house to make sure she was OK, we went for a coffee (nothing else happened) and had a chat, when I was going she got really upset and started crying. I text her when I had left her to make sure she was OK. She replied telling me to leave her alone and to stop texting her! Later that week I stopped over at my now ex girlfriend house, the next morning whilst in the shower she read my text messages and saw the text of the ex long term girlfriend asking me to leave her alone. She went hysterical and said it was over, I tried to explain but she said that I had lied and cheated to her and it was over. She has changed her mobile number and blocked my emails, I have sent her letters, flowers, tried talking to her, been round to her house in a drunken state to try to tell her how much I love her and miss her. All she said is that I should have thought about this before I did what I did and that she no longer loves me and she hates me and for me to leave her alone. I have even tried talking to her mum who got upset about it all and said "is that really how she feels?" and "your feelings dont change overnight" and that my now ex thought I was the one she would be with forever. After trying with the flowers and letters and crying whilst telling her how much I love her I decided to try to leave her alone so I sent her a letter telling its not what I want but I understand I have hurt her and she no longer loves me or wants anything to do with me and I will leave her alone to get on with her life. Its been a couple of days now and I have not heard anything from her, I'm so scared that I will never see her again and have lost the best thing to ever happen to me, I really don't know what to do! I mis her so much I know what I did was wrong and don't blame her for hating me. Im trying to leave her alone but is so hard!
