inconsiderate assholes 🖕🏻

So my mother and mother in law are both throwing me a baby shower sometime in march( I'm 28 weeks now) . I have this one family members who is freaking the hell out saying I'm a messed up person because I don't invite them to the baby shower. We don't invite them because they have a lot of hate and drama towards my mom and mother in law.. now these bitches are talking shit and saying that I have a problem and I told them that they apparently have a problem with me. They just keep being petty af talking all the shit. Then they say oh well your baby shower is not important to us anyways.. so I told them to screw off and since the baby shower isn't important than they have no business showing up to the hospital after I have my son.. what should I do about these idiots they keep hitting me up and talking trash and it's really stressing me out ...🖕🏻
