I need some opinions about this problem please!!!

1. Their marriage--their business. It's for them to handle, period.

2. BUT, in plural relationships (actually, in all relationships) negotiating and respecting boundaries is CRITICAL.

You're friend's fun with the married couple is commonplace; any bi girl has a lifetime of threesomes with married couples if she wants it. You'll see why if you ask any guy his feelings on FFM threesomes.

The husband's deception, on the other hand, is a FAT RED FLAG. Not only is it very disrespectful to the wife, but also--as you suspect--it puts the entire triad in a rotten situation emotionally: him lying, his wife suspicious, and your friend having to keep secrets.

Triads are possible, maybe even a good idea. But not this one.

She is certainly creating an environment where women can't trust their sisters, especially when the other woman has been so open and inclusive. You friend is contributing to a situation which does sound good. It sounds like this couple has bigger problems than your friend though. If he is going to be out of integrity with his relationship then it will happen regardless of your friend.

On the other hand the question is how is your friend going to feel down the road. I know a number of women who have been the woman who has affairs with married men and most of those women are pretty lonely. They are looking for something that the guy can not give to them and keep being looked at by other women as someone who can't be trusted.

My recommendation is for your friend to have a heart to heart talk with the husbands wife. Let the wife know your friends intentions. Is it to continue doing things behind the wife's back? I don't have a problem with threesomes. In fact, in the right relationship they work great, but the existing couple need to be in a good place. Your friend can tell that couple she will come back with they get into a better place. And have her stop doing anything behind the wife's back.

Wow, kids getting involved is horrible! You should alert somebody else about it because it smels like child molestation if it goes further! no kid should ever witness these kinds of things, especially child's own father cheating on child's mother. Does the man have no brain at all? His wife should leave him now. So should your friend. This guy is sick. And no one knows what they did to this girl, because I bet they would not tell you.

I think she just needs to stop. She is going to ruin the marriage possibly. And then what would happen to the kids if anything happend and people found out. She could ruin her reputation and theirs in the process. If they really want a three sum she should tell them to stop searching the internet for people and get themselves some friends that would. It is not a good idea for her to keep this up. I think she should stop now

I think they are all f***** up.
