I'm a jerk

I want you to stay.
I want you to be by my side every hour.
I want you to please me and ease me.

I want you to do these things, but I don't tell you as I don't think I'm rightful.
How come, then, -although I know you're putting yourself into this- has this kind of "you let me down" feeling arise?

I'm struggling with my feelings out of nothing.
Somebody, please, punch me in the face.
