Useless boyfriend

Boyfriend managed to not buy anything for our baby the entire pregnancy. Now baby is almost 4 weeks old and he still hasn’t bought a single thing! He just got oil (weed) and ejuice for himself. Stop at the store cuz I need diapers and he has no money for them. I have $10 in the bank, diapers are $9. So over it. He seems to make enough to support his bad habits but I gave all of mine up no problem.
