I feel like my baby shower will probably be a disaster. We are flying back from Italy then so it's no surprise as to when the shower is because I'm helping to plan it. My mom got all bent outta shape because her brothers wife (my aunt) was throwing out ideas for it. They don't get along but she was excited about the baby shower. I didn't see an issue but that's just me. Well since then my mom hasn't made an effort to talk about the baby shower plans or anything to anyone. I have mentioned stuff and she will just read my message but not reply. It's really starting to piss me off because why throw a fit if you're not even gonna follow through with anything!? Ugh. My mom and I aren't very close because she ALWAYS says she will do something for me then doesn't or lies. She is all about herself. I love her no matter what but I'm not looking forward to the drama lol & she hates that I get along with my dads gf 😑🔫 lord help me when we are all together! Ha
