Okay, for your girl problem, I'm gonna answer a bit.
I know I'm only 11, but in my 5th grade class, LOTS of things happen.
So, I'm going to say what others said, but a bit differently.
See, you can't make someone who doesn't love you, REALLY love you. IN my class, a lot of "guirls" like me. (Cuz I is hawt) One night, I got a phone call from a group of girls in my class. They lied to me, tried to force me into liking one of the girls who liked me. And I tried to reason, but these girls just can't listen. The point is, nobody can enforce love. But yourself in her shoes, switcvh it around. How would you like it if tyhere was a girl who liked you, but you didn't like her back? Wouldn't it be annoying?
I hope I've hel[ped explain a bit.
If you need any help, ask me, okay? ;)
