I have been with a woman for over 7 years now. We separated a few times and the last one was from March to May of this year. When we were separated, I was seeing this girl but never slept with her. Now, every time we get in an argument, she tries to use that against me. When we go out to bar's, she seems very friendly to all the guys and they all are her friends, but when we are together alone she is all over me. I am just sick and tired of that shit, but I broke up with her before and after a few weeks I miss her. How do I resolve this, I really want this to end, she always bitches and complains. When we go out, she never has enough, always wants to go to parties with me after the bar closes.
