I agree with flipper. Your husband sounds like the vengeful type. I've seen this sooo many times! In fact, I have a friend who had an alcoholic bum for a witness husband who finally had enough and left. He wanted her to sign a letter to say he was free. She was so fed up with him and the unsupportive elders that she did sign it even though she had not been with anyone. She just didn't care anymore.
She was df'd and her husband, the drunk, started pioneering. He came out smelling like a rose.
She is still DF'd and living a happy life. She is re-married and has a new career. It was all worth it in her eyes.
