Mind your own and it wsnt come at you...

Bad idea to get involved in either way. Avoid her and say nothing. If not, you'll be inviting unneeded drama and possible disaster into your life.

No. This is between him and his wife. Getting involved will probably make you feel better inside, but in the long run, it will destroy a marriage.

That is tough one...I think you should tell this woman, that she should tell her husband, what she is thinking and feeling on this matter! Because, this problem involves two people who are married. In this case, I can't see you stepping into this matter. Even worse, if he knows of your open marriage arrangement!

I think it depends upon the specific situation. Will the person you tell be more harmed or hurt by the information, as well as the specific motives of the person who chooses to tell. For example, of someone is choosing to tell another simply to hurt them or be an evil birch and it isn't that petson's business or in the best interest of the individual being told, then no, keep quiet.

I wouldn't but to each their own i guess?

Nope, not your problem and you'll be seen as the bad guy. Not a wise move, just get with the next one.

This is a time where you must exercise constraint, it has nothing to do with you,so mind your own business. There is always the possibility that the outcome could be disastrous and it will be on your shoulders. Given time, It could pass with no harm to anybody.

You know the saying “shoot the messager”

Are you sure she's actually cheating? Just being in a relationship and having sex with others isn't cheating if she has permission.

It depends on the husband. How close of a friend? Is she being reckless? Is she a serial "flinger?"

My gut reaction is no.

I'd say remain quiet... unless the husband/partner specifically asks, then just be honest.

Statistically, over two thirds of people "cheat", but most maintain mostly happy relationships with their partners. Coming forward without having been asked will only insure the creation of problems in the relationship. If a person asks, then they know problems exist and are just trying to realize or get a handle on the extent of the problems and how bad things are.

If it looks and smells like a pile of shit, do not step in it to test and see if you are right. Avoid it by walking a different path

No. He either already knows or will find it out shortly on his own. He will not hurt any less because you intervene. She may also go back home again on her own. Shopping around, doesn't always mean you buy something.

Don't tell him. That's not your business. The rest is up to you.

If they both are friends of yours they won't be after you rat her out. THAT said, I personally would love to be let in on the fact my spouse was cheating or looking to cheat. There's STD's out there and i don't like to see the innocent harmed any more than neccessary. JMO

Noooope. Mind your business & stay out of it. Nobody needs that drama in their lives. The truth always comes out one way or another, so don't worry about him.

Hey, whatever, but that would make you an asshole in my book.
