Your answer is FEAR. Fear of the unknown out there. So you're willing to stay in an unacceptable relationship where you have an adult throwing tantrums like a 2 year old.
I guarantee, when my first husband did that to me his azz was escorted out the door to jail by the cops and that was long before domestic violence was such a concern as it is now (1969).
Maybe instead of whether he is going to meetings or not and has a sponsor or not and has counseling sessions or not, you should worry about yourself. Are you seeing a counselor? And/or are you going to AlAnon and do you have an Alanon sponsor?
As we work on ourselves and our own self worth and self esteem improves then people like your H become toxic to us and we get away.
I will hope and pray that you take care of you.
Love and hugs,
