How do I get my best friend to back off my guy?

My best friend likes my boyfriend. How do I let her know that he is mine without hurting her feelings? Please help me so I don't lose him!

easy... in front of her
do what all couple do
kissing holding hands
if she still dun get it..
maybe just send her a message

I agree with fullofquestion.
There isn't really a good way to tell your best friend that he's yours without hurting her. You'll have to hurt her a bit, but she should understand, if she's really your best friend. She'll understand. So, the thing you'll have to do is to show some PDA in front of her? That's the only way to send the message. Stick to your boyfriend a lot I guess, and try not to give her a lot of space for her to get in and flirt with your boyfriend, if she does.
That's what I think...

Good luck :D

I think that you should show some PDA in front of her & if that doesn't work, then you should have a really good conversation w/her............goooooood luuuuucccckkkk!
