So you are free loading off him, his paying for a degree that doesn’t guarantee you a job. His paying for both your living expenses no wonder his resentful. I don’t really care what the others say who are telling you he has to pay this and that. Take away access etc. Your daughter is of school age, you could, should get a job. No offence your degree isn’t crazy intense. You could literally work when your ex has custody and do the shop/house work when she’s at school. I’m going to guess you don’t have classes 9-5 probably couple hours in the morning or after noon, after which you could study. I know people who have done PHDS and masters whilst taking care of a family and working. But he shouldn’t haven’t bad mouthed you.. ESH
