Go to the boyfriend first and give him the opportunity to tell her, then if he doesn’t and she’s a very close friend I would tell her, as painful as it is to find out she deserves to know

Should you become a gossip?
You already know that the answer is no.

was it you that was cheating with her husband ?

Losers who want to police. Break out the brown shirts.

You need to tell the truth I believe that if your not happy leave or if it's just sex tell your partner just be honest

I would want to know, but you may need to be ready for a "shoot the messenger" reaction from her if you do.

You can be anonymous, slip a note under her door, mail it to her, find a way to do it like that. I would want to know I"m wasting my precious time!! Some girls do know they just need proof. Please tell.

Just as much as men,and even more when you consider most of them have a "backup guy" in the wings...perhaps the question should be posed to include both genders.
Oh wait,all men are unemployed druggies who have several girlfriends on the go. But wait,no men ever approach any women in Vancouver. Confused now...

It’s normal here. People do that. Guys do that. Girls do that. Just embrace it and enjoy. You’re simply overreacting and exaggerating. Chill out. Jeez

Yes. Screw the whole "it's none of your business" shit. I'd wanna know. Woman to woman, man to woman, human being to human being. If it's wrong, it's wrong.
