I can't get over it

We were only a thing for a month, but we were having sex and so happy, at least I was. I thought he was happy, he acted like it, but last night at 11:30 he stopped by saying he "wasn't feeling anything" I know what he means though. He's an 18 year old college freshman, he wants to fuck around. It hurts because we were having sex, and he was so gently and caring, yet rough too, the good kind. Yet I guess it wasn't enough for him, because after going out and making out at midnight in the back of his car, and leaving a hickey, and holding me close to him, the next day he dumped me. Now I have this hickey on my neck to remind me. What's worse is HE initiated it, not me, and the next day dumped me like I was a hook up.

I know you guys will say "it was only a month get over it" but I can't, I should but I can't
