I'm hurt and cannot move on, Please help me figure out what I need to do?

3 months ago I've met a guy who I've become friends with benefits during the first week I knew him. It was ok for me, since I was single and didn't really mind a casual relationship. After a week of just hanging out in his room, we started going out.. we eat outside, watch movies, shop together, or I picked clothes for him, go on trips, we even went abroad together. We talk on the phone everyday, and we spend a lot of time together. I started falling in love with him.. I like him a lot..but he told me I'll be a really good friend, that he likes me and cares for me, but he doesn't want anything out of this relationship. He's not ready for a anything serious and that he has a lot of priorities in life, goals to achieve. Although, he made it clear to me from the start that he doesnt want anything.. but he leads me on. I do so much things for him, I act like a girlfriend.. and he clearly knows that I like him a lot since I tell him every time. I know it's stupid, but I cannot let him go.. or end everything because every time he calls.. I'll go running towards him.
