well, he my not show that he likes you but i know somewhere deep down inside of him he still likes you. so possibly he still likes you.
I think you should not be mean to her to be popular. She is your best friend, and if you treat her like a best friend, she will stick beside you untill the end of time. You don't need to be popular if you are happy when you are hanging out with your best friend.
he's not worth trying to help when he ignores and lies to you
When you talk to her and she ignores you.
Sounds odd that if you are a best friend to her, that when other people are around she tends to ignore you. Are you just a friend of convienence for her when its good for her? I would take myself over to where she is in the crowd and approach her as you would when your hanging with her elsewhere and see how she acts to you. If she still ignores you and doesnt include you or introduce you to others, then you have your answer, she's using you...Find better friends.
A true friend wouldn't do that. The problem is, you don't have a true friend. Don't worry, it happened to me once.
Sit down and talk to your friend, if he/she just ignores you, they aren't your friend at all.
Show my attitude ofcourse!! And try to make friendhip to her enemies
Just go up to your friend and ask him/her what happen between you to. if this does not work then your friend was not your friend to begin with. move on and find a norther friend.
Explain to your nana that you really like hanging out with your friend and that you love your nan but you wont stop hanging out with the friend because that would be unfair to the friend if she hasnt done anything wrong.
don't let it bother you. if he ignores you it's his loss.
she's probably either mad at you, or she has a crush on you, or one of her friends has a crush on you.
Hanging out and flirting are different, but there is a very fine line between the two. When your friend is in a relationship, you need to respect that.
