Most Helpful Guy
He probably is busy with life. Maybe he's playing video games and then checks his phone. Or even better he just doesn't want to seem too into you so he's being cool and detached.

He's probably busy? I don't know the guy I like takes more time to answer than I do (sometimes instantly sometimes 2 hours) but he works, goes to the gym, studies... So he's very busy and obviously can't be texting me 24h. But on the other hand he always texts me first soo... It doesn't bother me ^_^
