should i still be friends with her?

Only if you like people treating you like dirt.

This is a no-brainer.

so how do i tell or show her?

Be assertive and simply don't allow any one to play around with your feelings with intent to hurt, finding it amusing.

Assertive - she does not exist. Walk straight past her. She questions it and she will no one likes being ignored, "sorry, I don't need friends like you in my life" and continue walking.

End of story.

i like that answer but i dont want 2 hurt her feelings!

Well she hurt yours didn't she? Deliberately, thought it was funny, caused you embarrassment.

We only have people in our lives that are "true" friends. The rest are acquaintances that we can "choose" to be in our lives or not.

Being assertive means you know what you want out of life and you're not afraid to accept what you want and ignore what you don't want.

so maybe i should stop being friends with her, but how do i stop? what do i say or do? i also need help with the " my crush found out i like him" plz help me too

Already gave you my thoughts on the other thread

You can't do anything, she told him, he knows... You can flirt with some other dude in hope that he thinks oh, it was just a moment in time.
