At least your H is In therapy with you & is trying. You & your marriage must means something to him. A different counselor might be able to help you personally. Are you in individual counselling as well?
Mine won't even acknowledge that we need to go. He just wants Me to "get over it" and "pick up where we left off" pre-problems; infidelity, and that very large breach of trust is a very large hurdle to overcome.

I am trapped in a nether-world of pain and don't know how to get out either, so if you get any good advice, please pass it this way.
