About to lose my s*** !!

DD's dad coming back around last year has been nothing but a problem. He always finds a reason to argue with me over everything. I've been so nice and yet he still tries to argue. DD has a very bad prescription for glasses and she picked out some expensive frames. The total for her new glasses came to $225.00. DD's dad paid $160 and DH and I paid the rest. To make up for the extra money her dad spent I covered her daycare expenses the last 3 weeks (I only work 1 day a week) and paid for the laundry list of school supplies she needed. He was suppose to go school clothes shopping with us this weekend and all of a sudden couldn't afford it this week. He makes about as much as my DH has no other children and lives at his dads rent free so idk how he couldn't afford it. I asked him if he could afford it this weekend and he yelled at me for texting him while he is working. I still haven't heard from him and he hasn't asked to see DD. it's been a week and a half since he has seen her. We just spent $400 on new school clothes because she literally outgrew everything over the summer. Sorry for the long post. I'm just sick of her dad at this point.
