The share of people who keep secrets 'nem spring' of you

I know my friends are adultery, to his spouse bumper

The story is like this. Students back I played along with a group of 6 people. Two sons and four daughters. Among my girlfriend has a quite beautiful and both boys in the group to Italy. But she chose to love a person of 2 people. Their love lasts three years, thought out to the field they are going to do the wedding ceremony, but they break up in the time of both our groups. However, they are still very happy with each other, and always appeared in the fun of the group. Not long after, she I love you son, left in the Group and married him to do her husband. You're old lovers , go get married then. The rest we also had my husband and life stabilized. We still often bring spouses, children to meet and hang out together on the occasion of the birthday of the team members, or their children. This is all the team members all know. However, one thing that not everyone in the Group knows, that's what my girlfriend though took the others but still regular relations with ex-i.e. sons remaining in our group. Moreover, this relationship not only just started, but as soon as they parted from each other, they have determined that although the latter though is not "husband and wife", but they still regularly meet each other, to the relationship. And so on, is extended until now. This is just me and the two people that know, left others unknown, including the husband and wife, two friends of mine. I know this secret because once the other girls told me and told me I have to keep this secret, as if to say, her family and the family of the other boys will ruin, which is something she doesn't want.

But I don't know how do they stop?

When caught, I also met two people and suggest that they should terminate when no one knows, but they refused. They say, they can not survive if not "met" week 1-2 times. It is "habit" could not give up. Have it, wish I never dared speak out they secretly several times to introduce to me the man-as you can to their "modified wind" when sad, but I refused. So, I've been hugged this secret for years and at no time did not think about it. I see you I am extremely angry, but does not dare to denounce them. Because I know, if I told the truth, both of the families of the two men that would ruin, and their children will think nothing of their parents. Think I should remain silent. There are things he can silence, makes me feel peaceful, I always feel there is an error with your spouse and your children. I want to share with someone, but fear of the third person know then everything will no longer be secret, so I share here we wish readers can give me an advice.

In addition, also through this sharing, I want to tell my friend that, let's end this crazy action before it is too late, because I was bored with the role kept confidential for two people. If two people does not pausing, I'm also not sure that the "secret" is continuing to preserve. Thuyan ...=
