I have the same sitch as slowly, My W pursued the OM. I have no harsh feelings for OM. I don't respect him because of what he did to his W and my family. However, I have compassion for him because one day he will get caught and loose his family. I wouldn't wish the pain of the LBS on my worst enemy. I've been through this twice and I thought I would be tougher this time, but it hurts more this time because I love her more.
RJ, follow your heart. You have a loving and caring heart and if you listen to it, I know you will do the right thing.
