Well please don't judge but I think.(Just think)!
I might be attracted to a girl in my grade And I don't know to tell her.

I have absolutely no intentions on judging you! YOu might or you do have feelings for this girl? If you have feelings for her or you are establishing feelings for her, for me, is no different than it would be for me to tell a guy I have feelings for him. Question is do you know this girl really well? Also, what grade are you in? Can you have an honest open-hearted conversation with her? Honestly, I would just tell her that you have feelings for her

I think you should get to know her. She may not be open to you liking her. You don't have to express everything you feel. Get to know her

Agree with Homegirl. Be friends, show you like her, and see what develops.

You may like her, but she may not feel the same, so start as friends and see how that goes.

How old are you both?

Me and her are best friends for life!

You said you think you might be attracted to her. Why do you have to say anything?
