rant: Me and my little ones dad don't live together so we planned on spending the day together tomorrow . well I had let my mom know and my grandma had asked if I was busy tomorrow so my mom had told her. well every time she finds out were spending the day with him my grandma flips. Saying he's not nice, he should be around our daughter. he's not ready to be a dad and he's not a good influence. and list goes on and on she seriously makes him sound like satain or something. ut got to the point tonight it had me crying. they've only meant each other a couple times and they've barley talked. and I don't tell anyone what goes on besides my mom and my mom doesn't tell my grandma anything other than we go over or we had a little disagreement.

Advice? am I overreacting? do I confront her about it?
