hhhmmm, well if you really want to be his friend give it a try
By telling him
You ask a friend to tell him for you :)
It depends how much you know the friend, if the friend has never lied to you I would believe them.
I know that a friend is a friend if they like me for who I am and they always listen to what I have to say and never leave me behind. i also know that a friend is a friend when they don't share your secrets and enjoy your company and don't exclude you
No, your friend will blame you for telling her. I know you are trying to be a friend, but she won't listen and you will ruin your friendship. She will need you when it does come out.
I assume you are a girl and she is your friend. You need to keep this to yourself if you want to keep her as a friend. I know this will be hard, but your choice is telling her and loosing a friend or not telling her and keeping a friend. I would say keeping a friend is better than not having one.
If he likes to spend more time with your friend rather then you that would be one way of telling.
you could try telling him yourself, or get a friend to say it.
just talk it over with your friend! and if she doesnt listen, you know she was never a true friend in the first place!
Obviously they are not your best friend then - be straight forward, honest and polite and let them know that you can no longer be friends.
tell her that she might be broken when she finds out he is cheating and just tell her the truth and say its your choice to breakup with him or not but i know that he is a cheater and leave the subject alone because she will get mad if you keep telling her
they are always staring at you and telling there friend you are ugly but they know that the LOVE you
