Habit: I have read your sitch and I have been going through this for 6 months. No affair, wife is in MLC. You have detached physically but you have to detach emotionally from her-hard to do I know but time helps. Also, try taking advil pm or some other otc sleep aid, you will be amazed how much better you can feel with a good 6-7 hours of sleep each night. I took it every night for 2 months and have not taken since because my body adjusted to getting sleep each night. No sleep, high stress and emotions are not going to help this at all. I would also recommend getting the kids and going out of town for a few days without her. I have done this a few times and it makes a big difference. She needs to know what it feels like to be in an empty house since she is going to feel like this half the time if she gets her divorce.
