Do something for yourself, it's always good to keep loving yourself. This is scares me about my wife threatening to stop all of her activities outside of the home. She needs to get out, to do things, have friends. Only in the last couple of years has she really made some good friends.
I say GAL.... Oh and pray too, pray that your H will come to realize what he has with you and get through the pain he is feeling from his FOO.
