Children’s father won’t help out

We’ve been broke up for about a month now. He sent an email saying if I needed anything for the kids, to let his mom know. BUT before I do that, I need to check my integrity first bc he isn’t going to support someone who isn’t progressing forward or isn’t worried about the kids future, etc. I’m in nursing school, working towards my degree, and anyone BUT him will say I’m a damn good mom. Also, I want to add that not only did he say this, but also asked if I’d drop his domestic violence charges 🙄 so I should have integrity before asking for diapers/wipes, but should basically forget my integrity & drop his charges lol. Here’s a screenshot for any confusion. I apologize for his grammar 🙄 this man makes 80k a year so he’s not stupid. Just can’t text.

Edit: I can’t go for child support right now. I can’t miss one single class or I’ll be on probation. My next break won’t be until May-July of next year where I won’t have classes. He’s also said before that he would rather lose everything he has & sit in jail before he pays child support for this same reason in the email.

Another Edit: I don’t plan on dropping the charges!!!
