Yeah, i agree with missamo.
On one hand u still have strong feelings for him, but if he does not care for your, then you will be hurted lot more in future by this fact.
So i suggest you to move on with your life too, try to forget him and do more stuff with your other friends and eventually you will meet new guy.
You just need to be strong now with cutting the bound, if you manage to do that it will greatly improve your relationship experience in future.
So if you are under 20y line, don't worry. Life is still young and there is no need to bound yourself and suppress all the good in you. So put a smile on your face and say to yourself '' screw him, i'm going to do something really nice today''
My suggestion? Go out with friends have a blast, or if they are not available, GET ice cream and watch really nice anime.
Hope anything of that helped.
