That FB thing - I'm not sure how deactivating an account makes you look single. That would be a strange consequence of simply going 'quiet' on FB for a while. So I'm not convinced by that.
You were pleasant and not aggressive on the phone; that is a positive thing for you. Don't worry too much about how he views that, though I understand it's really hard to not over-analyse everything they say/type to you. Jsut distract yourself with something.
