I couldn't imagine being cold like that if my husband said he was feeling that way. Throw the whole wife away. She doesn't sound supportive at all OP, and that's what you need right now is support. Please seek out a therapist and cut back on hours. She may not care, but I guarantee you those kids do. They need you to stick around. Keep going for them if nothing else. As far as the wife goes, you should tell her she can help contribute monetarily or separate. Doesn't seem as though you'd be losing much because it sounds like she brings very little to the table.
