We´ve been together for 3 years and everything was just fine until she stopped having sex with me, i´ve tried to talk to her many times but she insisted that she doesn´t need sex that much and is not even thinking about it because she had stress at work etc.

I know she cheated before on her previous boyfriends as i went through her old messages and emails. I got her facebook password and everything so i knew her every step and what she´s discussing with friends. There was nothing strange at all. I knew she´s close with her colleague (we were working in the same company all 3 of us) they were always talking but not hiding or anything so i didn´t pay attention. Later they started going out shopping and for lunch but nothing happened as i was watching they facebook conversation real time after she came home so she hadn´t chance to delete conversation with him. He wrote to her that he likes her a lot but she replied she has a boyfriend at home and will not cheat on me. Not for a long time...

I flew home for a week to see my parents and friends and that´s when it happened. She called him to watch movies two days before i came back and they got drunk and he fucked her on our sofa...remember i had access to her facebook so i knew right away what is going on...i didn´t confront her but i knew she wouldn´t keep it for herself for a long time so day after she finally admited that she fucked him and was terribly pity about having sex with him and said  it will never happen again and i can completely trust her from now on. So i did, but then it really started...

They started to fuck even more at our place while i was doing night shifts or at his place as well, she said that she loves sex with him...i confronted her few days later that i want to break up and i told her i know everything, first she tried to convince me it´s not true but then she admitted that she fuck with him again. She even did it day before my birthday and day after as well. Strange thing is i was pissed off with her but the whole thing was making me horny at the same time. I masturbated a lot thinking about all the details i could read from chat. I know this is probably strange and you´ll think this guy is fucked up but i just couldn´t help myself...i forgive her whole think even though she wasn´t able to answer my question why she´s having sex with someone else but not me. Now we are separateed and she changed her password so i don´t know if they´re still fucking or no.
