Does your bf give you as much attention as you want?

I'm dating this guy and he sucks at texting me back. He says he is busy with hw and stuff but I mean if he really likes me he would text back more often right? Sometimes he takes like over 4 hours to reply. We aren't bf/gf yet but he says he basically treats me like a gf which worries me because I would want more attention as his gf. I only see him once a week. Maybe I'm just too needy idk. Suggestions?
