need advice: cheating friends... why the he** do people stay in cheating relationships!?

[Anonymous]

ok say you have two sets up friends...

the first couple are not married and they have always had somewhat of a disfunctional relationship. they have 4 children. the female in this relationship has a history of cheating.

then their is another couple who are married and have two children. their relationship is ok but the husband has a history of cheating. the most recent was just a couple months ago. 

now you and your husband find out that the cheating female from one relationship is cheating with the husband of the other relationship. how you know this is because they call each other and text all the time. flirt and when the one females SO is at work the guy who is married is parked outside their apt. at 1:30 in the morning. 

my question is do you tell the other people?

why or why not?

is it your place?

i will say this i am a married woman with young children. i have never in my life cheated married or not. so i do not personally stand for it. i personally would want someone to tell me if they new my dh was cheating on me. would you?

why would someone stay time after time?

I'd leave it alone and find some new friends.

I would want to know, especially if my so called friends knew

I would tell them if I knew for sure.  I wouldn't want to be friends with cheaters, so it would be no loss.

Personally, I would let the other spouse know.  As you said, if my dh was cheating on me, I would definitely want to know.

TELL THEM. Make sure you have concrete evidence and know you will more then likely loose some of their friendships.

I would just stay out of it. As much as I would want to know if my SO was cheating on me, I'm not getting into someone else's drama/relationship.

what would concrete evidence be?

i once had someone tell me they would never believe their husband was cheating no matter what proof anyone had unless they walked in on them themselves....

Quoting Anonymous:

You tell them, and you will get some major blame. You have to ask your self whose friendship is more important. If the cheater is more important, talk with them and see if they will come clean themselves.

Like someone said earlier wait until you have concrete evidence. And just be ready for them to take it out on you I.e. 'shooting the messenger.'
