More than just a hookup

Does anyone have any tips on how to get out of the just a hookup zone. I’ve hung out with a guy a few times and we always laugh constantly and he always texts to make sure I got home okay after. Anyways he’s made it pretty clear he “doesn’t do girlfriends” but I can’t help but think it’s just me. Recently we started hooking up and he seems really into me when we’re together but not so much otherwise. Any tips to leave him wanting more? Or make him fall in love with me lollll

We had sex on Valentine’s and he told me “I never make plans with girls on this day”... what does that mean hahahahaha kill me
