The next difficult step, of course, is how I approach dating. I worry that I'm in a healthy state of mind to begin any sort of relationship. Maybe something casual would be okay.
Personally I think that if you're ready, then it would be a good idea and a great way for you to more effectively put the D behind you and become more detached. It sounds like you plan on easing into it and that's a good approach, but things do have a way or progressing rather quickly if you make a connection with someone! Just try not to let it move too fast, it's like going for a swim in cold water, you have to ease your way in and adjust before moving in further. Then again, maybe you're one of those people that just does a cannonball right into the cold water, LOL!
