Bless your heart. I agree with the others in that this must be totally devastating. I cannot imagine having to put up with this, especially since you have no family or real friends to fall back on.
I would be not only hurt, but incredibly mad! To think that he could do something like that would really infuriate me!
I too think that I would issue some sort of ultimatum. Either he agree to some sort of counseling for HIM or else I'd seek the advise of an attorney, and if I were you, I'd take him to the cleaners. Take 1/2 of his pension AT LEAST, and a good share of his savings/investments and anything else he has!!! Afterall, HE'S the one who ruined this marriage! I don't know what state you live in, so you'd have to check the divorce laws there. But I'd sure take what I could! Don't be "nice" to him out of compassion. He doesn't have any compassion for YOU.
You might consider getting counseling for yourself, dear one because your self-esteem is in the pits. You are a good, kind, beautiful person! Don't let what he has done to you change how you feel about yourself! God bless you my friend, and take care! Hugs, Lee
