Most Helpful Guy
Things like this are really common, especially with online dating. It's pretty much guaranteed that you're getting at least a dozen connections per day on Tinder, most of which you ignore. This guy has lots of options too and what he was probably doing was keeping you as an option in case his better prospects didn't pan out. Being that he disappeared completely, it probably means that he has lined up some better dates, but it's very possible in the future that he'll contact you again with some hokey story that he got hella busy so it'll be up to you if you want to buy that story. I wouldn't.
