I bet you'll never know the size of the bullet you've dodged here with her rejecting you. Trust me, from the sounds of both your threads you're waaay better off moving on. I think you're right not to be friends with her, she's probably just been using you to fulfill the emotional needs she doesn't get from her boyfriends. When you look back on this from a real relationship's perspective you'll be glad things turned out the way they did.
Sorry, but seriously, she gets her tubes tied in her mid-20's because she doesn't want to have kids???? And now, because of her nephew, she's thinking of reversing it? Sounds like a keeper!
