Thanks for your input.. Yes, she has a good job and is capable of supporting herself. She has a lot of debt, but that is her issue.
It will be VERY hard for me to financially take care of the home by myself, but not impossible. (I pay the mtg, W pays the utilities/bills).
My concern is me being able to control my emotions/behavior/detachment while under the same roof. I know I will try, I worry about my showing any weakness or bad DR behavior.
