friends or spill my feelings out ??

I’ve been friends with this kid since my freshman year and we’ve both like each other on and off but never at the same time and we never exactly worked out. We’ll we ended up sleeping with each other and I feel like that was all for him and in the moment it was for me too but the sex was so good. I like him a lot but this time he isn’t feelings it , i want to keep sleeping with him but I don’t if I’m going to keep falling for him. What should I do??
