I posted before but wanted to get into the subject of my current bf's ex. I guess I should start by saying she has always been a sore spot for me and I can't seem to wrap my mind around why they were ever together in the first place.

I know she should have a place in our current relationship but somehow she does...to some extent.

My bf dated this gal before she ended her marriage. He assumed that because she moved out of the house she had lived in with her hubby that they were on their way to a formal divorce.

My bf dated her on and off for a total of four years. To me that is n drop in the bucket.

This woman has caused a lot of discomfort for me (when I was just his friend) and others he cares for. She was known for just showing up where he was. For example, he had gone on a trip to Vegas with friends and she claimed she just happened to head out there last minute as well.

She visited his mother in another state without him knowing it. She hit on his brother in front of his brother's wife and then inferred that his brother's wife was a bad mother and heavy weight wise.

She set up his facebook account and would delete people she didn't want him to be friends with. She moved into an apartment right next to his...for a while.

She would demand that he end his friendship with me and when he refused she would end the relationship only to come running back when she was "drunk." I suspect she would just use that as an excuse to meet up with him and lure him back in.

As the relationship died down it came out that she had lied about getting a divorce and that she had actually moved back in with her husband and was trying to get pregnant by him all while trying to give my bf an ultimatum that he agree to marry her and have a baby with her in the next year.

She did so many strange things that irk me. She started flying to NY to hang out with my best friend as a way of getting information about me. Why? I have no clue...I used to think it was because she thought I was a threat.

Fast forward to today and I can't help but dislike this woman. She is a disgusting person to me. She was manipulative, strange and just plain wrong in so many ways. I can't believe my bf would be involved with her and for so long...

I kind of get eaten up at the idea of him being with her for so long. I don't get it. To make things worse he would mention things like her favorite movie when I hadn't even asked about it. He still has gifts she gave him. He mentioned that a girl in a tv commercial reminded him of her (not in a good way) and it all just makes me feels almost sick inside.

Does anyone have any advice on how to let it go? I mean she has no place in my life right now but I hate that she is a part of my bf's past (especially since his family and friends will bring her up).
