If your'e still looking for something in yourself, which it sounds like you are, I don't think your'e going to find it in him or anyone else. You mentioned always wanting something like this, but he is a person not a thing. I'm really into exchange theory in terms of relationships, and are you sure you can contribute as much or more to this relationship than you expect to take out? For that matter, if he's a normal guy, lol, he's going to want some sex eventually...which leads me to the last question, what exactly about him scares you?
I dunno, maybe with some more background it would seem different, but my first instinct is to say woah nelly.
