I didn't like what I had become either when I walked way from my abusive, psychotic EXAH.
However, I thought leaving him was the solution to my problem.
Although that was part of the solution, what I failed to follow through on was to look at why I was attracted to people like that.
So for 13 miserable years after I left him, I kept making the same mistakes over and over, only with different men.
I second the suggestion of getting your hands on a copy of "Codependent No More." Find local Alanon meetings in your area. There you will find face to face support from those who have been where you are..
I have also pursued therapy/counseling over the years as needed when I have issues crop up that need intensive work.
I'm sorry for the circumstances that brought you here, but I am glad you found us!
