Who can help me deal with an ex-wife?

I guess I just would love to vent to people who don't know me, my ex-husband, my boyfriend, or his ex-wife. She is manipulative. They have been separated for over a year...him sleeping on the couch for about 3 years prior. Long story short, they never really liked each other. However, what a disaster. She wields her "ex-wife power" (or more like, soon-to-be ex-wife) any chance she can get. Who else deals with someone like this? An ex-wife or an ex-husband? Let's vent...

People do what you let them do...she's an ex..nothing more..there's a reason why there called x. Only obligation is if children are present..even then..its what's best for them..not anyone else..

I am dealing with this type of person, I am hearing you, yes it is an ex but NASTY causes issues for everyone, anyway, I decided to remove myself as much as possible, seriously who needs her insecurities. I never knew her before and do not need to know her now, my husband he can do as he likes as he has children with her but he chose to remove himself as well, his children being adults are not happy with the situation but it is what it is.
