Should I text him again?

This guy and I snuggled last Monday and we fooled around a little. We didn't have . I haven't seen him since then. He and I have talked via text up until last Thursday. He told me he doesn't want to use me for ***, and he just got out of a 2 year relationship. He told me he likes fooling around with me, but I think he's trying to put things on hold so he can try to make this more than just hooking up. I want him to text me now, but I hate waiting. How long should I wait? Should I even bother? We both had midterms last week and since he's premed, he's been super busy and told me that. I just want to know would it be stupid for me to text him first? And if you think I should wait, how long? Do you think he wants a relationship again?
