I would have to agree, before I got married I was with (not sexually) this girl that I met in the bar, We walked down the beach and kissed and held hands. I was drunker than I had ever been and had to go to work the next day. I felt very guilty about what I had done, and when I finally did confess (btw my wife knew about it) It was like I was still not able to breath, because I knew that my wife would think about it every time we were intimate. To this day she may still. The guilt that I felt was worse than any pain you can ever imagine. To look at the person you love and promise to spend the rest of your life with and keep a secret like that from them will break you in the end. My suggestion, if you have fallen out of love with your husband recommend that you start to reconsider the relationship and give him a chance to express what he feels. I would not go off all willy-nilly and be with someone else, especially my best friends spouse.

So NO DONT DO IT!!!!!!!!
