what would you do.

I agree with all of you it is what I have been doing the past 8 years, refusing to allow myself to get caught up in this mess. There are things I did leave out. This guy was brought up to "Take Responsibility". We were on and off and never labeled it. On an off time he was seeing another, we lived 50 miles apart and when I returned he went to cut it off and was hit with a bombshell. I knew before I was even told, (another reason I know) I had a dream he was chasing me around his home town with a "shotgun" he shot my foot and then began to "tend" the wound. He said he was "sorry, for the pain" but he had "no choice" and to "never let go" When I woke I told my aunt who looked white and said "shotgun wedding" so I contacted family who were up there and was told that indeed is what happened. I sent him word, that I understood. Back about 4.5 years ago when he confessed all. She'd come to me a few days before that all upset over them fighting and that night she was going on about that letter I had sent. She questioned me on the meaning. I was stunned I did not know how to answer her, and I hate lieing. So I did the only thing that came to mind and looked him in the eyes. He wasn't impressed she questioned me and blew up at her told her to mind her own business and stay out of his past. Thats when he took me outside and admitted everything because at that point I only knew we had split, and he ended up marrying her. Though I know why he stays I don't understand why he stays, when hes not happy. Friends have noted it its documented in pics, and friends even comment how different he is around me vs around her. So I was confused if by standing my ground and holding strength for both of us, if I truly am doing the right thing. Or if he is waiting to be told what I assume him to know, before he makes his choice. After all he is so much like me that its possible he sees it, but can't believe it until I tell him so. Like he did with me.
