I was married for 5 years, no kids, which ended last month. I had an affair with a girl in my office for 6 months, at the start it was only friendly talk but developed into something more very quickly. The girl knew to start with that I was married but we still continued. We slept once in the initial stages but after that the girl always wanted to avoid it so never happened again. However I did fall in love with her and told her that, we became much closer over time. However at one point she said she loved me as well and suddenly after that wanted to stop seeing me. Long story short we went through a month of hardly talking to each other but again after that she started seeing me again on a regular basis. She has always said that she dint have any expectations from our relationship and that she wanted to find someone she can settle down with.
All this time I was cheating on my wife so yes that makes me a low person, call it affair fog or whatever but I did feel in love with her. Now couple of months back my wife found out about my affair and everything was hell, worst thing is I cared for my wife a lot, she is a lovely person but stopped loving her over the last year or so. My wife even confronted the other girl and she confessed to what had happened. At this time my wife and I separated for a couple of weeks and the other girl contacted me a few times trying to help the situation and wanting to meet my wife which I refused. Anyways two months of counselling and arguments with my wife, we finally divorced last month. I feel very guilty of doing this to my wife, very lonely as well now but I deserve that, but I also know I couldn't have made her happy going forward.
Now the situation is that I met with the other girl again yesterday and I completely know that she has no expectations to go forward with me in life and she said that clearly yday. She says she feels guilty of spoiling two lives and destroying a marriage and that she just wants to move on start a new life. I still love her and she says she feels the same. Every time I see her at work she always talks nicely to me and having said she doesn't want anything with me yesterday called me to have a coffee today at work (we used to go for coffee breaks quite regularly). She is moving to US in two weeks time for good as well.
Now I don't expect her to marry me as she was clear about that to start with but what I do not understand is that if she doesn't want anything in life for me and the affair ended two months ago, why does she still talk to me, why does she try and be nice to me or send me confusing signal (talk to me in office or calls me in office but doesn't want to after work)..she says she doesn't want to get attached again or raise any expectations as she also went through a depressing time in the last month after what happened. Over the entire affair, she has gone hot and cold about the situation but continued to see me. Now she doesn't want to, which is fine, but why not just say that and not talk at all. I know I need to control my feelings but because I am an idiot and love her and that she is leaving I don't ignore her. Please advise, and please feel free to criticise me for my behaviour, there isn't much lower in life I can be right now. thanks
