Friends? Situation?

A few months ago I lost my virginity to my best friend. Two weeks ago we had sex again for the second time. Part of me wants to be more but at the same time I’m not trying to waste my time since he gonna be graduating soo. We used to be really close but now we don’t y’all as much. He usually text me when he wants to do something honestly and I don’t know how to go about the situation. What should I do?
