Husband won't seek help

I just found this website, I am so thankful! I'm on the verge of leaving my marriage of 22 years because I do not know what else I can do for my husband. His behavior is destroying our marriage.  I've tried for years to encourage him to seek professional help. He won't go. After finding this website, I've discovered there is a psychological name for his actions all these years. I believe he has one or more personality disorders.

What can I do to encourage him to seek help? Several years ago I went to counseling myself, hoping to learn ways of dealing positively with our issues. It only worked for awhile. We need marriage counseling together, and I believe he needs  individual counseling as well.

I don't want to abandon him, but I cannot live this way anymore. He has to take the first step to get help. I can't do it for him.
