Suzie,
I'm glad everything went okay.
But i know exactly how you are feeling, as I am sure we all do. I am also sure that the feelings of "its not over" will soon fade. Its not actually been that long since you split up, so just give yourself time...get on with your own thing, and above all dont close your mind to seeing anyone else once you feel ready.
If NC worked before, then it can work again. He contacted you, yeah? He'll either be back in touch with some reason that he needs to see you, or he wont. If he does "need" to see you, just go and do what you did today...show him how happy you are and how well you are doing. If this doesnt give him a kick up the backside and show him what he's missing then nothing will.
But remember, if he wants to get together as just friends, it wont work while you still feel like you do, having the belief that its still not over, so dont plan on doing things together until you feel healthy within yourself.
I probably havent made much sense cause its late, but you go girl!
Well done on today!
