To stay or divorce?

I have been married for almost 5 years. My husband has had issues with alcohol and depression since the beginning of our marriage but quickly spirled when i became pregnant. During my pregnancy he was very disconnected. He often told he shouldn't have gotten married. Hes not up to the challenge etc. When i gave birth it got much worse. After coming home from the hospital and.having a c section my husband told me he.didn't want to pick up after me. His drinking led him to have violent outburststowards me and himself. During our marriage he often threatened.to.harm himself. Yesterday we had a fight over his drinking and he smashed.my phone in front of our 1 year. Idk what to he doesnt want help. We've tried counseling ultimatums and even a.3 week separation when my baby was.8 weeks old. Im so tired and heartbroken. Im also a.christian but a big part of me really wants to leave.
