Hello Reddit,

This is a throwaway for obvious reasons. 

I had been with the woman whom I htough I was to marry for 5 years, but she recently left me for various reasons. Now, 4 years prior I was unfaithful to her, she found out about this and, according to her, she had forgiven me, and it had not played a roll in her decision to leave me. The person whom I slept with was a dear friend of mine, and quite honestly has always been the girl of my dreams, we had been friends since secondary school. In the 4 years that had passed since this incident she got a lot done, she had another child and she is now married. After this whole ordeal that my break up has been I decided to contact her and she how she was doing, she seemed happy and was very happy for her, that is until she told me that she was very unhappy with her marriage and she had missed me those 4 years that we could not talk. At this point and time we are talking to each other almost as if we were a couple and we are exchanging photos and the such, but nothing has happened recently. No one knows what is going on between us except for some friends of mine that do not know her. My goal would be for her to leave her current husband and stay with me, I am more than willing to take her children in and of course marry this girl, but she keeps saying that she doesn't want to divorce her husband because deep inside she still loves him and she doesn't want her children to go through their parents divorcing. Any advice is welcome and appreciated.
