Drunk husband 39weeks pregnant.

I'm due in five days with baby #2. My husband has been drinking every other night for weeks now. Pass out drunk drinking, not social drinking. He starts with 6 then gets more and more. He says he's stressed about our finances which I get, and we should be, but he just left the house without telling me (he's drunk and is on his way to a party) and I cannot stop crying. What if I go into labor? Instead of my MIL coming here to watch my son overnight I'd have to wake him up (he's 2) to take him to her house (which he refuses to sleep at) so my MIL wouldn't have to deal with drunk husband whenever he shows up.

I told him when he got home from work today that I feel vulnerable and like he's acting out and I'm by myself in this and that I wish we'd spend a little time together as it's our last week of having some free time. He said he understood and would just have a couple beers.

I don't know what to do.

He has a problem. He doesn't care enough to Really get help. He's had DUIs in the past.

So upset and trying not to stress myself out anymore at this point.
