HL...
I am writing this to let you know how normal you are and to share my experiences as well.
I found out about my W's affair almost 7 months AFTER we divorced! Her affair was over 4.5 years by that point. I was still crushed beyond my wildest dreams. I am a pretty big guy myself. A big machismo guy of Sicilian descent. I lost 75 pounds! I was not eating or sleeping. I went to IC 3x a week!! D-day (to me ) was not then, it was she confirmed it during our attempt to reconcile. It has been over a year since D-day...almost 1.5 since I really first heard of it and it STILL HURTS. Her betrayal of me was complete, she threw me out in the garbage (via the courts), took my house, my children and my money. Then to find out that my 5 years of ****** previous to that was due to a long ended affair just put me over the top. I did not want to be here...or anywhere...it was really...really bad. IC helped me big time and I am quite unashamed of that. Without it I believe that I would be dead right now...
However, I still loved her. What I did after that mess was "go dark"...sort of a plan B. Would not see her or talk to her except about my boys. My IC strongly recommended it. After time she saw me for what I was, not the man I WAS. It takes time my friend a lot of it. I struggle with this every damn day. However, my struggle is not alone. She struggles and finally had to "face the music" for her own actions. She is harder on herself than I am.
HL..this will take time. I will tell you that we're in a much better place now than we EVER were and we were married for 15 years, dated for 3!!
Good luck HL...
