I know the emotional roller coaster is tough. Thought I was off it for good but tonight threw me for a loop. But it's not as bad as it was before, only one or two rides before I got off. So jump off! I know, easier said than done. I wish I could offer advice how to detach better. For me it was only when I decided to drop the rope and move on that I really felt detached. I also allow myself to feel the feelings and let them go. Silva passed on a good method for doing this that also helped me a lot. Check his old thread, I think #3, for details.
Just try to do the right thing in every situation. And if you pray, ask for the wisdom to know what that is and the courage to do it. That's the advice I got from Puppy that really helped me through.
If you love somebody, set them free. http://tinyurl.com/2empx2g
