Cathy, IF you can, and yes, I realize how difficult it is... stop worrying, thinking about H. You need a breather. I know he is there in the house, so it is difficult, but you need to put the whole thing out of your mind. Really, really try to focus on YOU. When I post a lot, analyze a lot, it really only puts me in a dark hole that I choose not to be in.
Getting out with your GF tonight will help. Laugh, enjoy. Stop wondering what H is up to, etc. YOU can do it, you are the queen of detachment. You are too close, and there is STILL nothing you can do about H, he STILL has to figure this out on his own.
Step back.
Read a great book, read the Bible, get reinvolved with something for you. Refocus. Just another ride on the rollercoaster. You can do it.
Relax. Appreciate. Be calm. Laugh. Enjoy. Be secure. Be loving. Be loved. Don't personalize. Don't ASSume. Accept. Be grateful.
