Alcoholic husband

My husband is an alcoholic, not abusive towards my child and I but I'm tried of it. We have a 3 year old and a baby due in December. I'm not entirely sure what I should do, he won't get help because he said it doesn't work for him and I will not leave him. He usually drinks 2-3 times a week so it's adding stress on me because that's a lot of wasted money. He won't change for our kids or me I have no idea how to get through to him. Things won't change unless he wants to change but I'm running out of options.
