So this might sound selfish but I really dont want my SOs sister to come to the baby shower. His mom and my mom made a event post on Facebook for the baby shower and his mom invited her. She put maybe she would attend but I really want to tell her I dont want her to come. Ive meet her twice. Well kinda meet her. she wouldn't even say hi nice to meet you she acted like I wasn't even there both times. Her husband is nice and talked with me but she didn't even acknowledge my existence. She talks bad about me to there other family members and she doesn't even know me. I've tired putting myself out there to start a friendship with her but she just ignores me every time. I know that if she comes to the baby shower it will be miserable because shes the kinda person that thinks she better then everyone and anyone. Is there any nice way to tell her shes not invited or should I just hope she doesn't show up?
