Sol, I agree with UA. Take time and think things out before acting on anything. You are right that she will deny it and then more than likely you will lose your cool. That's what I did when my H kept denying it. He finally admitted it and even said we needed to work on us, he came home for close to a week, but then retreated back to his cave saying he needed space. In hindsight I would have done better working on detachment more and then confronted him when I was level-headed. This is so hard...I know. Just come to the boards to vent to us until you have figured out what you want to do. Take a deep breath and pray.
Life's challenges are not supposed to paralyze you, they're supposed to help you discover who you are. -- Bernice Johnson Reagon
