SO2, I am with B - find more to engage yourself. I did the same most of this year. I stayed late at things, or arrived early, made up things to do, places to go, hobbies, etc. My boss loved it b/c I got so much done - my point was to stay busy and tire myself out.At one pt I thought about getting a pet. At times I got desperate and started chatting with my kids' friends - that was weird for all of us. I think my kids felt bad for me but often wanted to get away as soon as possible. LOL!
I agree that it hard to detach when children are involved, but look back, you had kids with exh and still got out and M. People manage - it isn't perfect but it gets figured out.
