My husband thinks he wants a divorce?

I still love him but he wants a divorce. We fight all the time and he drinks when he is mad. He has called me a shitty wife etc. I know I'm in a bad relationship but I don't want to just jump ship because we fight. We've almost been married for 2 years and we are both 21. Yes, I know young. What do I do? I don't want to become another statistic
