What should i do???

I met this guy at my university and we were cool I went over to his place and stayed there for a couple of days unexpectedly. We got nasty but when i left I found myself developing feelings for him. Idk if its coz I haven’t had that feeling for a while for anyone and wasn’t sure if i just liked him for the attention. He was very nice and respectful when i was over, cooked for me too. Later that month I told him I had feelings for him and he told me he doesn’t want a relationship and is busy with school and his businesses. I was fine with that, got over it. But recently he texted me to come over to get nasty with no strings attached???
