Friends with benefits

I met this guy and we were a “thing” for 2 months and were super into each other hanging out everyday for those 2 months. Then he ended things because he wasn’t ready for a relationship because he said he’s still so scared of getting cheated on again. He kept telling me and cried to me that it was nothing I did But still wanted to be friends. Then after to being just friends for 1 week he wanted to be friends with benefits so we have been doing that for a couple of months. But I still like him more than just a friend and he started talking to other girls while still fucking me. And that hurts me knowing that I wasn’t good enough even though he claims I am but he’s “not ready” but talking to other girls? (I’m 17 and he’s 18) How do I move, and still keep our strong friendship but not be constantly hurt?? Help I need advice!
