what does he want from me ?

im 24 y.o. & So I've been great / best friends with this guy for like over 6 years I've always known he really liked me , maybe even in love? Would do anything for me. I've recently started to fall for him and we finally hooked up. He was AMAZING in bed I didn't expect that from him at all! So things remained as normal we even became a little closer ,hanging out more etc. but then when I ask him about us he says he's sorry he lead me on? He doesn't like me like that? yes continues to be with me everyday , stay the night , cuddle , give me anything I want . So am I crazy? Is he using me ? I need help I'm starting to love him so much but I don't want to feel used or like he's getting the best of both worlds .
