To add to my earlier post, @Here we go again, it seems that you may suffer from codependency, which is when a person sacrifices their own needs and self respect in order to fix and resolve someone else's problems, when that someone else is hurting you and is harming your own mental health. This man is hurting you and your mental health suffers, yet you are still willing to help him and you want to save him from himself and from his mental health issues. That is codependency. It may benefit you to get a therapist, if you do not have one already, and to perhaps join a codependency anonymous group for support and help. I used to be codependent. There is no shame in this.
