i feel you on this id have a lot of thoughts on my mind too if i were in your place.
There was this one guy i was talking too we met online but he had gone over seas around australia and japan. We never met in person before but yet he'd always call me me and write me and send me a lot of gifts... without having met me.
But for your situation i'd say he is probably busy.. because he seems like he might be a real decent guy.
GOOD LUCK and hope he is safe and he gets in contact with you. <3
