I'm done. So unfair.

I'm so done with my mom right now. I'm the only reliable, responsible kid she has. My s.o does more for her than her own son does (my brother) yet she continues to treat him like shit. She bends over backwards for my brother and his girlfriend. Borrows them money they never pay back. They always want to throw their kids at her and never care when her birthday or holidays roll around, while my s.o and I go out of our way to make up for what my other two siblings don't do. All we ever ask for is for her to babysit every now and then, but it's rare yet she acts like we're always asking for something. Anytime we've ever borrowed money, we've paid back immediately. My youngest nephew is turning 1 in October and there she goes already planning a birthday party for them when they make more money then she does. She's never tried to plan anything for my son and while she bought their newborn a swing, my newborn only got a couple of onsies. I'm so fucking done going out of my way to do things for her. My s.o and I even moved out of our apartment to move into get house to help with financial troubles, yet somehow that means nothing. Yesterday I made it very clear how done I am. I've decided to stay away for awhile and keep to myself. I'm done with toxic people/things in my life.
