Carter has never felt this way; he's so in love with you, and he doesn't know what to do. It scares him after everyone in his life abandoned him and left him to be alone; he can't handle the idea of you leaving. So, he leaves first.

"God, don't you get it? I just don't want to be with you," he scoffs; the way he clenches his jaw and fists tells another story.

Carter can't even look you in the eyes while he breaks up with you. After a full year together, he realized he was falling in too deep.
