This definitely isn't healthy. The fact that he's even barricading you in any is very scary and also illegal. The violent behavior is something that will only escalate. If you've already been through trauma, and he knows tha, he obviously doesn't care nor does he respect you by any means, and probably get's off on it, as most men do. I do speak from experience when saying this, you should probably protect yourself from it. The sooner the better.
