drunk husband

my husband is pretty great most of the time. he can drink beer or hard A and never has a problem with violence until whisky comes into play. last night we went out with friends to a bar and I only went because our friends are great and want to make sure I have fun so we found a bar with a ton of games we play. 
my husband started getting drunk and I asked him to slow down because I don't want him to regret something and by getting that drunk he's throwing the fact that I can't drink in my face. he was totally understanding but then he did 4 shots of whisky. 
20 min later he gets verbally violent and says that if I cared about our baby (15 weeks pregnant FTM) I wouldn't be in a bar. I tried to leave and walk home and he wouldn't let me. went home and he was just a fool. saying im weak and a coward and a horrible mom and lots of other stuff. throwing things across the room and then kicked the unlocked door in. 
I don't know what to do. I work full time in a high stress job and pregnant and have no one to talk to.
