we like each other but...

he's not looking for anything serious but he said he's into me. we're physically attracted to each other but he's not at a spot right now for something serious.
and after that text we still talk like before, he'd flirt but i wouldn't. and he asked if i was upset, im not, just understanding. what can i do with this? like i don't want to feel like i'm being used for my body. we haven't had sex. we kissed but never did anything further.
