Oh Steph.....you may never fall "out" of love with the guy. That 1% that draws you is no more going to change than the 99% that you know is bad for you. But those feelings don't mean you have to be in a relationship with him, especially because you know just how bad an idea that would be.

If you can manage to be a friend for him, let the love become a dear friendship, through this time....then that's a blessing. Stop yourself from behaving as though he's a boyfriend, keep up the proper boundries, and keep looking for emotionally healthy people to fill that role in your life. If you can't do that while he's still in your life, and only you can know if that's something you're both capable of, you have to walk away....even if you're still in love.

It's all about loving yourself at least as much as you love the person you shouldn't, I think.

Good luck with it.....I hope you find peace with the situation. It sounds like a real tough one. I know how it can break your heart to have to walk away from someone you're convinced needs you. Wouldn't want to do it again.
