Drama never ends.

^please no hate^ i was seeing this guy.  Who lied to me about being married in the beginning. Well he finally told his family he was separated and brung me around after the first year. The wife who he hasn't been with for 3 years, is legit crazy always starting drama with me because she is mad he don't want her, she would message me the whole time telling me to keep him that she was happy he was happy, then would turn around and text him saying I was talking crap. So it's nothing new. Since we broke up a few months ago he has another girlfriend. But I'm about to have his baby and I let him know that I'm dilated so that means she's making her way out. He chose to tell her about it.  She got mad and unblocked me starting liking my posts from a year ago on his Facebook, posting his pictures, and commenting love stuff. I cant help but laugh because I know she's feeling their daughter and her will be replaced, but that wasn't going to be the case. She tells him all the time to stop contacting me for good because all I want is to fuck him over, and that her n him are coparents that I need to respect.. So she wants him to take care of their kid but not mine. All I asked him for was 175$ this whole pregnancy and told him I just want 80$ a month for diapers after she's here, she asks for a car her bills paid. So who's fucking him? Not me.  Lol but we've been getting along great. He's been over 3 times this week and we just hung out to work on our friendship for when our daughter gets here. But after this stuff started happening I got pissed and told him "you can thank her for ruining your final chance for us to be on good terms ✌🏾️" they aren't together so I'm mad at him for even telling her our business. Do you think I'm overacting?
