What I notice, is, he always makes time for you. It feels like, despite the distance, you two have seen each other quite frequently lately, more than you 'should' want to see an exgf. I find that confusing. Maybe he really respects and admires you and wants to genuinely be friends. Or maybe theres something else in it. What does your intuition tell you?
I was curious as to why you said you werent going to snoop on FB and see if he was seeing someone or not. I guess if he was, that would explain his behaviour. But then, like you say, he would not likely want to go to dinner with his ex when he just got back into town if he was seeing someone.
Seems you are keeping a good friendship going with him. Personally, I think you two need to loosen up and have a few drinks together.. well, worked in my sitch!! He said an awful lot of revealing things once he'd had a few ales, as we say in the UK. Maybe its a British thing.
