I would not recommend it. If you're young, it is most likely not going to last long. Besides you wouldn't want to be known for going around your ex boyfriends group now would you? If you do not think this advice is wise, you"re just going to have to learn the hard way.
be happy and visit them
If you still like your best friend then try to get her back or let her go with your sister if that's what your friend wants. Or mabey your friend could be friends with your sister and best friends with you.
Reject her.
If you like it, kiss him back. If you don't, break away and tell him, "No!"
If your best friend is honest and caring and looks out for you then he/she would be your best friend but if they're mean and say nasty things behind your back then they are your enemie
Your best would come back because he still values you. And it is for that reason he has best attached to it.
If your friend decides to stop talking to you, it is usually just a phase, and after some time, she'll come back to you, if you really are best friends. If her new 'best friend' is changing or having an influence on your real best friend, you should try to step in, saying that this is wrong. If you're worried, the best option is always to just talk to her. As the phrase goes, 'If you love something, let it go- and if it comes back, it was always meant to be. If it doesn't, fate had other plans.'
just tell your best friend that you really like him and see what she says about it.
It means that he wants to become your best friend. There's nothing wrong with him bring your friend unless you have a problem with it.
becuase arguements with your best friend are what hurts most and it comes out through anger.
Give them a gift.
You date her best friend
