Remember the vows you took, I didn't and I've lived to regret it. For better for worse. You agreed in front of God and family. Now get help, get him help. He won't want it at first. Maybe get the courts to order the help. Therefore get the police involved. Divorce does not solve the problem and all these people are too quick to throw away marriage. You have twins, they need both parents. It's better your there to supervise how he treats them rather than send them off for visitation.

I let people talk me out of marriage. I regret it. My life is unhappy. My exes have all moved on. Don't get divorced, work on solving the problems, one step at a time. You vowed to stay, once you break that vow it's broken forever. Don't get divorced. No one cares why no one cares why your divorced they just see a woman who gave up, didn't try, won't try. You'll be miserable raising twins alone. Try and fix things. Try.
