H did say his therapist made a point of saying nothing is permanent-that people marry and divorce and remarry all the time.

K, you live for you and your kids, and you fix yourself. When or if he realizes his path is the wrong path and turns around, you might be there for him. That is up to you. This is all up to you. You do not see it right now, but you are in control of this marriage...not him. Your relationship isn't over until you say it is.
