Family vent

Ok so my mom and bio father r divorced and I got a new dad and now a new mom?!

And my bio dad (abusive& alcoholic asshole btw) invited my mom, dad n me to brunch with his new gf?! To like celebrate my bday?! Which is tomorrow not today XD. Last year he didn't even know how old I was lmao he thought I was 14?? 

His gf iz a cool person btw and she txted my mom to ask her if she can call the cops on him FOR THE 2ND TIME HELLO?! I'd say break up but to each their own idkz. But I get along w her n I like her but my bio father was still a bit of a weirdo but at least he didn't drink this time cuz i woulda cried xd
