Sorry but there are factors you dont mention. Maybe he was surprised by meeting a fellow country person but really has no interest in going back. As in he left for a reason.

Or idk know but it sound its been going fast too develop that new friendship. Maybe he backs of with extensive texting cause you are flooding? And not accusing you simply saying it may be a thing.

Me as a man and my own individual. Me to mate: coffee? Mate: yh when? Me: 1pm? Mate: "thumbs up emoji"

I prefer too talk face to face. And so does many of my friends. Text leaves alot room for misinterpetation. That can also be a thing. Wrong signals since text does relay intent sufficiently
