Yes, I know what you mean! These terrible situations turn us into great readers! I've lost count how many times I've read DR from cover to cover since November and I sit reading and reading on these forums hoping for some sort of miracle inspiration, that one thing that is going to fix it. I know it doesn't exist of course but somehow the searching makes me feel useful.
As a woman I cannot understand what your wife has done at all. I cannot imagine abandoning my children. There is nothing in this world that would make me do that. Thank goodness they have you to be a rock in their lives, bless them. I slipped up and asked my H if we could talk the other night. Apparently, according to him, we have talked. Not enough for a 19 year relationship, 15 year marriage and 2 kids we haven't, I said. He just walked away. He's getting really good at it.
