Hi psychfan,
I'm so sorry this happened to you. I went through a similar experience 4 months ago and am still struggling with it. Like you, I can't go completely no contact because I work with the guy. My guy got married to his new woman right away. So like you said, each day I go into work the wound is re-opened. I feel used and betrayed and humiliated. I have made a no contact policy for myself meaning that I have no communication with him other than that which is required to do my job. Talking about it with friends has helped. Not all of my friends understand how I feel, so I don't talk about with the one's who don't get it. I don't know if I have any good advice for you. I can tell you that it will become easier with time to cope. I can tell you, as some small consolation, that most likely he will do to this new woman what he did to you. You do need to deal, accept that it is over, and move on. He probably did love you but the love has flamed out. It's over. Give yourself time to grieve the end of your relationship and then as soon as you are able, try to focus your efforts on meeting someone new. It's hard. I have fantasies of my guy coming back to me and telling me he made a mistake. He's married for God's sake and I still have this fantasy. I feel crazy. Not sure if this is reply is at all helpful.
