Parents have an instinct which cannot be denied, if I were you I would put myself first since you do not have kids think about if this is what you want for life.

What he did to you is called ABUSE. Do you know or have an idea about his childhood or background as to how his parents lived? Happy, Unhappy, broken?

Please do not try to work part time just to fit his needs or desire you need start working full time and start having a life of your own. You rushed into moving in and saying things like I love you too soon. You wont know a person even if you have lived with them for years and three months is nothing, we cannot go back but you should never ever have moved back in with him.

Its good he is showing you signs of improvements but please for your sake think about your self first. You need to make sure you know what to do if this out break happens again. ( If it does pack your bags and run the 5K away from him and never return).
