Been in this exact situtation and in hindsight I'd point out a couple of things...
Firstly, listen to your intuition..it's bang on!!! how is it making you feel/think?
Secondly, Dont go to him...if he feels the way he does, he should be coming to you. If he doesnt, ask yourself why?
Thirdly, knowing his family doesnt give any knowledge into his life apart from he isnt married...
My honest opinion is he is a predator...but that is based off the guy I knew and uncannily almost everything you are saying is how it was with us! Tiki gave advice which I discarded, regretfully...
I can see he has already wormed his way into your heart and it is a hard thing to now STOP the way you feel, living for the next time you contact each other. But try and look from the outside in.. is he truely exerting himself at your disposal...or are you just convieniently there at the right times, the lull times? When he talks of future...is he working his way to you or just painting pretty pictures of what could be???
Be careful, look deeper, listen to others around you...your friends are also bang on! If they say nothing it's a warning...
