For whatever is worth with my crazy past. If you go back to your old life, accept that he his that way. And it won't change. If you accept this fact and go there with that mindset. You can make it work and live through it with how he is. If you go there hoping to force him to change, you will just waste your time.
This is my learning experience from a lifetime trying to get a family filled with abusers.
From there, you do whatever you want. It's your life, your decision and you will be the only one living the consequences of your actions.
