That is fabulous! I can relate. The pit in your throat when your thoughts move from your mind, to your voice and then to her ears is excruciating. There is no putting the genie back in the bottle. I am so happy that you did it and it worked out well for you. I find that if the mutual love is true and deep then a SO will accept one’s dressing. This does not mean she has to agree with it or want to see it but just accept it for who you are and that it is is part of what makes you you. For me the burden of carrying the secrete around for so many years weighed so heavily on me that I was quick to anger, quick to dismiss and withdraw frequently. Upon telling my wife I am more relaxed, open and giving. I am a better husband as a result of it.
Good luck in the days to come and keep us updated on your progress.
All the best, Jamie
