i think when you know, you know, and it sounds like you were able to tell based on the lack of chemistry on the phone. i don't think there's anything wrong with that.. you're going with your gut and looking after yourself. that being said, i don't think it'll hurt to go and have your "condition assessed" - and at this point what do you have to lose? if you don't clique with him, then you've not lost anything (as this was something you already knew) and if you do hit it off, then great!
