bad snapper = not interested?

so this guy randomly snapped me out of nowhere about a week ago. turns out he's SUPER cute and he's my exact type, like if I could make a dream guy it'd literally be him. we've talked a bit (got to know the basics about each other and all) and he told me he's not just looking for a one time hookup and wants to see where things go. however, he kinda sucks at responding on snap (he'll snap me randomly a couple of times a day, but will leave me on open for a couple hours at a time). in his defense he does go to military school and plays a sport there so he legitimately is busy, but I also just don't know if this is a bad sign or not. I'm looking for something more serious so if it were up to me I'd rather talk way more often or even text or something (we don't have each other's #s). i normally think too much into these things but idk if I should legitimately just take it as him not being that interested. i'm not sure how much of a social media guy he is bc we haven't been talking for long yet. what would you guys do in this situation? does this mean he's prob not interested? (we're 21 btw)
