I am sorry you are having to deal with this "man baby" it is like having 2 children. Leave. Get a divorce, and allow him to pay child support, you will be better off with out him. As a bonus, after the divorce, just move out of the state. Stop yelling, begging, reasoning, belittling him and leave. I was so happy after I left my son'd father, for similar reasons, I was a better parent. Heck, I was a better person. Get out now!
