K,

After having gone through this myself, I realize that our feelings are usually right. I am not saying that your husband still loves the OW, however, if indeed she existed and he did love her in the past, he is definately mourning. Different people mourn in different ways. Maybe a "real" seperation would help you both realize what you are giving up and if it is worth fighting for. Don't know what else to say.......Sorry this is bringing you down.
