My boyfriend refuses to talk to me?

We are constantly fighting and bickering, we are never intimate and if we are it is on his terms. I have tried every day to talk to him about our issues and try to get them resolved so we can move past them but he refuses and says he will never want to talk and if I push further he has even gone as far as locking himself in the bedroom or leaving the house. What do I do? Do I just drop it and work it out internally or do I leave him?
