Bf drinking problem

Hi everyone I’m f (28) my bf is (29) we have one child together and our biggest issue is my bf drinking. I never wanted to be that girl to tell my bf he can’t hangout with his friends or go out to the bar with him until recently, he’s been getting out of control drinking, getting wasted. Not wanting to come home, we just found out that I’m pregnant.. He goes out with his co workers at 6pm and by 10pm he’s pushing the time back and back. Yesterday I had to pick him up at 12, he was so drunk. Almost threw up on the bed.

I feel so depressed and confused.

We wanted to get pregnant, we spoke about this.

I’m getting to the point of telling him I don’t even want him going out with his coworkers anymore because I can’t trust him. He doesn’t know when to stop but a part of me also feels bad for telling him.

Please, any suggestions? Opinions
