>>>maybe you can start first by thinking about what it means to you.For example.. does his being happy with someone else make you feel like you will get less attention? Did you have hopes of finding a close relationship similar to a marraige with him? Were you romantically attracted to him? What does this new marrage mean for your relationship with him? <<<

thanks for all your responses so far.
Yes all of the above. I am really nuts! I know this is not reality.that nothing could ever happen between us. I know this logically. I don't think himgetting married means anything to our relationship. But I cannot get over the fact that he is with someone. At night when I am thinking of him.I'm jealous!
