Friend having affair.. advice please

Hello all,

Not been on here for ages but would appreciate some advice. I have found out that one of my best friends has been having an affair. She has confided in me and another close friend. The dilemma I have is that although she has been a good friend to me through my own divorce 6 years ago so has her husband who was hugely supportive also. I think her husband should know as he is absolutely breaking his heart and is blaming himself etc etc.He has asked me if she has anyone else and I have said I don't know. I do not condone her actions and feel I can't lie anymore. What a mess.

Would appreciate any advice ?

Been in that situation and basically my advice is not to take sides.
As usual the innocent one is often last to know.
Yes it breaks the heart of one but if you get involved you will become an enemy of one or both. One will blame you for not saying and the other one will blame you for spilling the beans.
Then of course there may be the possibility of them getting back together and you will be out of the picture as far as both of them is concerned.
I wonder why your female friend confided in you. Guilt? Someone to share a problem with ? Or hoping that you would tell the guy to save her from doing it. There is the further possibility of her boasting about it.

Not a comfortable situation for you and virtually the only way for you is to have as little contact as possible and be prepared for the outcome. Which side you take if any is up to you.

I would tell the best friend that she is obviously not happy in her marriage if she is having an affair, so SHE should tell the husband.
i would keep my distance from this pair until they sort it out
