Dear, letmeno said it! You'll get to meet a lot more young men in your life - and you should never make them the center of your world - it's not worth your self-respect and valuable time. If they choose to use you and then pass you on, they don't respect you and know they can play with you. You don't want that for the remainder of your young life!
Move on and mark this one up as part of the experience you'll be gaining for a long long time and learn to grow stronger each step.
Tell him to take a long walk off a short peer and meet new people.
Concentrate on your education and your future goals - without counting on anyone else except yourself. Then you will be mature enough to read a relationship and have enough confidence in yourself.
Good luck, and please keep us posted.
You deserve better - now go for it.
