Money issues help

I need help with this. So this is my first year claiming my baby in my taxes well i did get 5K for my return and her credit. Honestly i buy about 95% of her things and her dad once in a while provides for her. He did his taxes and received 3K. Yesterday, i finally got my refund and he’s going nuts asking for half of it… saying that he should get some of it. We live together but i am financially responsible for myself and all my expenses. He pays $690 for rent and about $100 of electricity bill. I provide all household items and groceries and other necessities… he’s going CRAZY for $$. He started saying that i wasnt shit and that i was stupid for not giving him anything when i pretty much buy her everything. Im not stingy with $ but the way he treats me he aint worth it. Am i wrong?
