How can you tell if a guy is interested after the first date?

Sounds like he cares more about u than ur body, very good signs, idk if he cares about u considering u dont know too much about each other, but im sure he cares about u as a person, he cares for ur emotions i guess i can say, and 9 times outta 10 thats the kind of person u want, but idk the guy, but keep ur eye open there are a lot of snakes in the gr who start off that way
