I've been hooking up with this guy on and off?

I've hooked up with this guy before and he never texts me after we do but this time I've hooked up with him twice within 3 days and even took me to eat one of those days. He’s been texting me ever since asking me about my day and stuff. Is he actually interested in me or just trying to string me along just for hookups?
