MotownJohnny,
I would say once you know you want to continue dating someone, and you feel like you can let them in, tell the person what you feel comfortable disclosing. I wouldn't get too deep into the relationship before letting them in on your issue. If they're the right one, they will be OK w/ it, and you're right, they won't want to try to save you. Unfortunately, it takes some of us a while to figure that out, but it's a vital lesson to learn. When you feel ready, go out and try to meet someone. It gets harder the longer you wait. I regret not getting back out there after my ex and I got divorced. It's just so hard, but you just have to do it.

Best of luck & let us know how it goes!
