What would u do if u found out that your wife had sex with her half sister's brother?

This situation is eating away at me. I really love my wife but after finding out about this it makes me sick everytime I look at her. I mean she kept this from me for almost 10 years. This guy even came to our wedding and other gatherings, now that I know I see why he avoids contact with me or acts antisocial. I feel like throwing up and killing somebody (not going to proceed with the killing). How can she have done this? It would have been okay if it was some guy or something. And to top off the situation when we were dating she stressed so much about how she hates lier, deceivers, and whores, but the whole time this is what she has been doing. I really need some help and advice on this.

Before this destroys your marriage, both you and your wife need to see a marriage counselor and work through this.

They say you can't unring a bell. The question is will you be able to get over your disgust? Take time and think about it hard.

I agree with both of them! That's some good advice!
