What is happening to you is not of your creation and certainly not of your choosing. I grew up living the cycle of abuse. I can still feel the tension build half a century later. Please read the article.

You can do nothing. You can go to Al-Anon or see a therapist or both (If he lets you). You can see if he will agree to joint counseling. You can call a local safe shelter and decide on a plan to get you safely out of the house if need be. You can ask him to leave with the understanding that as long as he keeps drinking he is not welcome. You can leave if he will not. You can get a legal separation or a divorce.
What you likely cannot do is stay without paying an exacting price.
Good luck.
