You know what I find interesting about your H is that you are D'ed, but he still continues to act like a MLC'er with you. Isn't that interesting? I think many people here need to hear that. The legalities are all taken care of, but he still feels the need to mislead you, etc. Your opinion of him still matters to him, thus the lying. You should continue to stand for however long you want. Even if the D already happened.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
