My ex’s baby mama is a weirdo

I mean this girl is..like really weird. Her and her mother. They have always been nice to my face, and I’ve always been nice right back because that’s just the type of person I am. But these girls..they have talked so much crap about me that I’ve heard from their cousin. Saying I kept him from their baby and all this when I’ve never ever involved myself in those matters unless he was venting and wanted my opinion on the situation. She kept their daughter away from him because he doesn’t want to be with her and because I was with him.

After we broke up, his mom ended up telling them why. And of course she starts letting him see their kid. Which really, if anything good came out of that, then I’m happy for him. But now she’s telling people she wants to make me jealous. I’ve seen her recently and she went “hi, my name”. In the most condescending way. I said hi back. But I’m annoyed. Annoyed because I was nice to this girl when everyone had something bad to say. I gave her the benefit of the doubt because I didn’t personally know her and I wanted my ex to be able to see his kid without her having an excuse not to. But I’m just a nice person. Way too nice for my own good. And it just shows that doesn’t even matter. When she puked while getting shitfaced, everyone laughed at her and I made sure she was okay. I hung out with her and actually tried. Im just..I wish I was mean girl who would have given her something to smile about.
