Depressed and dealing with alcoholic husband

He's a VET and has a heavy drinking habit.

He promissed to stop as soon as I'd be pregnant but it's been almost 8 months and nothing.

I don't have any family here it's just me and my 9 year old boy from a previous relationship so add home sick on top of that. He's not aggressive when he drinks, he just acts really mean. He absolutely ignores my child even when sober, when sober all he does is scold him for silly things like leaving the bathroom light on.

I'm emotionally a mess I've even started self harming again.

I can't talk to him about my feelings and I'm so scared of seeking help and getting locked up in a psyche hospital and leaving my kid with him.

He has a daughter who spends the day with us, she's the only one who he's nice too even when he's drunk.

We're always fighting to the point I sleep in another bed and cry myself to sleep while he snores the night away.

I've tried talking to him in so many ways I'm just so tired. I feel like just having this baby and leaving the baby with him and going back to my family with my son.

That's the only solution I can think of
