Alcohol problem feeling guilty

My husband have been married for 4 years now with a little guy.

6 months into our marriage he was speaking to other women behind my back/sexting etc. forgave him, went to counseling. He did it again and again, I planned to leave him and found out I was pregnant. Things were great it was like a new start but found out he was doing the same things and started drinking even more.

He is overly jealous/verbally abusive while drinking. He’s called me a slut and a loser. I told him I was leaving after finding out he was again texting other random women. He got super drunk, said if I leave I’ll be a target for men and that they will just use me. HONESTLY I DONT EVEN HAVE THE ENERGY TO WANT DATE OR GET MARRIED AGAIN AFTER THIS. It’s been years of this verbal abuse.

Now I told him I want a divorce. He said he is willing to go to AA and change, I feel guilty for wanting to leave when it “seems” like he is now willing to put in the work but I am mentally not okay/have anxiety/insecurities and don’t have the energy to feel like I am even a good mom right now 😓 just really feeling it but I know I have to stand with my decision to want to leave right?
