Thanks everyone for your responses. Even though it seems i am not taking your advice, i am listening and using everything you say to decide my future actions.
Natus, thanks for your responses. I am starting to see how deep my wife lies. You see, I have private emails and messages from her to my BIL with some information on her actions. I purposely ask her questions that I know the answers to to see if she will come clean. Of course she lies...
The trap I am trying to avoid is revenge. I do want our marriage to work, but part of me still wants to get back at her and make her life miserable for what she has done. It would be all too easy to do this. That is why I am agonizing over outing her to my sister...I cannot decide if that's just me wanting to make my wife pay at the expense of my kids and may sisters kids.
The other thing I take into account is that some people responding are on their way through a divorce...I'm not sure their advice is best for keeping my marriage intact.
