Success stories of Long distance between countries ?

Hi everyone, A couple weeks ago I met someone (in person) while on vacation and he’s great-he checks off every box for me. However it was going to just be a vacation fling but now that I’m talking to him I’m starting to develop feelings. We live in different countries and I’m just wondering if this could ever work? I’m in the US and I think I would be miserable if I went to his country. I don’t want to apply too much pressure to him because I’m not sure how he feels about it and I think I’m it’s far too early to say anything like that. Anybody on here have any successful long distance stories of different countries?
