I wish I could say your circumstance will work out. If you had asked me the day before all this started what I would say or do if my wife was to leave me, I would have said she knows where the door is and it is one way. It was not until I realized what I had done and I may have lost the only person in my life that meant the world to me. It still is not all roses. The other guy got fired so is not in her life daily. We are getting stronger. I have asked her if she would let go of him and not communicate or see him if he contacts her. It is still her decision to make, but I would feel better with out his presence in her life. Daily we get closer and them farther from what she has told me. I am not sure how your husband will respond. He may not realize the gift he is going to lose until it is to late or ever. You have to stay true to your self. what ever you do don’t lie or cheat. It only makes thing worse for you. If you are to move onto someone else then make a clean break. Then what ever comes after is not tainted by deception. All the best and good Karma for your life’s path. We only see a little of the path we are on, but it is still your choice which way to go.
