I was engaged to the most incredible man in the world until this past New Years Eve when I found out he had fallen in love with someone else. We were supposed to be married in a few months and we had it all planned out, including where we'd live, etc... I agreed to raise our kids Christian for him (I'm agnostic), I transferred from an old job, I became best friends with his sisters and their husbands. We were really great friends before we got together and we are really close with a tightknit of group of mutual friends (who have been great about not taking sides, but neither of us want to sacrifice those friendships just because we broke up). I knew this would be a hard breakup, but I thought we could get through it with dignity.

Except I have to see him with his new girlfriend everyday. We're both teachers at the same school. And so is his new girlfriend. I thought I'd be able to handle it, and for awhile we settled into a really solid post-breakup friendship, but recently whenever I see him at work he has eyes only for her. I feel like he continues to lead me on by being very sweet and funny when we're alone, giving me signals that he wants to repair things, but as soon as she's around it's like I'm just a fly in his ear.

Everyone is telling me to "forget him", but I don't know how. He's so loving, acting like we'll work this out, and then just brushes me off to be with his new favorite person. I see him everyday. I'm still crazy in love with him. Plus a part of me is hoping really hard that he'll wake up and we'll fix this and get married like we were supposed to, so I'm not really committed to idea of getting over him.

What in the world am I supposed to do?
