Need a Plan for My Marriage

[LSG]

I am starting the process of exposing the marriage to the OMW as soon as I have the personal information. Is there a best way to approach for best results. I feel bad for her that she might be hurt from this. I have to do, but I do not have to like it.

My wife wants to take the kids to a work event, but I want to be there so I can keep the OM away from them. She does not want me to go. Should I stay home or go with her? Any thoughts?

I need to protect my kids from this infidelity as much as possible.
