>>all I want is to spend some time with her,talk with her, play with her, hold her hand and hug her.

This sounds like a healthy relationship for an adult to have with a 7 year old. Love does not always mean sex, and love does not always mean romance. Don't try to be her boyfriend; she's too young to know what romantic love is. Be this kid's friend. Be this kid's confidant.

And do be careful, and remind yourself that you can never, EVER, do anything to hurt or compromise her.
