An End to a Story

I liked a girl for several months. I finally got up the guts to talk to her, and she said yes.

I have her now, but I don't want her anymore.
we're three years different in age and I'm going to college. As hard as she may try, she just can't and won't be able to understand where I am in life right now. I like her, but I'm just not at a point in life to be in a relationship.

She loves me. but I know I don't love her. I have to break her heart which breaks mine, but in the end it's the right thing to do.
