anyone good at writing that can help me out.

Ok so my bfs uncle hates hates me for no reason. He took my bf outside today and started talking mess about ME! Saying I need to get a job instead of laying down. That they're there to take care of him not me. That no one else would say it but he would. That if I'm pregnant. Ok so first off I applied places just waiting for the call back. Second he has no right to complain when he's still living with his mom laying on her couch at 32. He has money but rather spend it on getting drunk and high. When he asked if I'm pregnant my bf said no and he said good. He doesn't take care of me or my bf like wtf. So I know it sound immature but I need help writing something that is towards him. So i can put it on Facebook. Putting it towards him but not saying his name. Anyone wanna help me?
