Need a Plan for My Marriage

[LSG]

The other man says he is having problems at home. My W told me that his W cheated on him a while ago, and the are no longer in the same bedroom for a long time now. Should I believe what she has told me he said to her. How will this impact me when I expose to the to his W. Will she be able to help me and her to end the affair, or am I screwed. He seems to want to end his marriage this year for my W. Many question I have. I am eager to talk to the OMW about this situation and see if he is lying. I need the correct approach to be most effective. Then I will set up the boundaries very soon. The sooner the better I think. I just need to consider what will happen, and how I can do it best.
