Im having a roommate issue and need legal advice

I moved in with my boyfriend and his brother last year. We need to pay one more months rent and it'll end the lease but he's refusing because he says we owe from when we moved in since he paid $1000 and my bf and I paid $890. He says we owe $370 to make it even but we never agreed to pay it back and now he's acting like a child not even caring if we go to court. What can we do?
