Bum ass baby mama vent

I have a hard time getting over what a bum her mom is and the fact the courts gave her full physical custody despite knowing everything. Her mom had her maybe two days a week for a couple hours at a time when they gave her full physical ( he let her have her whenever she wanted but she never wanted to and often didn’t show up even when she said she would). Even now the kid is with us 50% or more. CPS has been involved multiple times for neglect, hazardous living conditions, and potential abuse. Mom refuses to take her to the doctors, gets mad when we do, and refuses to follow a doctor’s orders. She even lied to doctors which almost resulted in the kid being on medication she didn’t need because she didn’t want to admit they had bugs. She doesn’t want to brush her hair and take care of it properly so she just cut majority of it off. We take her to school and pick her up EVERY DAY, even when she’s at her mom’s. Mom never has her in clothing that fits even tho we’ve sent lots of clothes and had family send clothes. Him and his family have supplied all the clothes and shoes since they split and if they don’t she just squeezes her in random shit. I’ve literally seen her sent in baby clothes ( I’ve never known her as a baby or anything close). She tells us it’s not needed yet the kid tells us she doesn’t have shoes or a coat there ( which she didn’t until we sent it and kept asking for months). Her mom drops $100s on video games, weed, and makeup on a regular basis yet they don’t have clothes for her kid, shoes for her kid, a car, ect. How do both of you have well paying jobs, 6 kids combined, and no fucking car? You’re telling me two working people can’t afford even a used car after 2 years? They only have 1 kid all the time most every other weekend. He pays her child support, she receives government assistance for food and health insurance ( she told us that’s why she won’t give him more time on paper unless he fights it in court). This barely even scrapes the surface of all the issues. It’s just straight bs and I’m over it, honestly have considered leaving because of it.
