Thank you Elya for some good points. Here are my own thoughts.
First of all. WOW......... I'm Speechless. This is a
very BRAVE step and shows that you are in this struggle until the very end -
for real. Again, you have shown you are not afraid to jump into the Yam Suf up to your nose, and rely on Hashem.
This revelation to your wife can be a big help to you in the long term, but I am warning you that you should brace yourself for some pain in the coming days. It is very painful for a woman. Women are emotional creatures and knowing that her husband had a whole fantasy world with other women in his life, even if they were only "virtual" women, is very hard for her to swallow. Until now, she thought she was the only one in your life.
At first she may show understanding, or even "no response" - as in your case. But it will sink in and she will feel lots of pain. You may find her crying a lot in the coming days. You need to humble yourself and take the pain, and keep silent and show her extra love. If she throws anger and abuse at you, tell her you deserve it. Tell her that you are HAPPY she is so angry at you because this way you will be much stronger NEVER to break her heart again. Tell her how her Neshama agreed to come down to this world to help you in your Tikkun, and part of that help is that she will be there as a strong deterrent to you never falling again. Promise her to only tell her the truth from now on. Tell her you don't want to live a life of hiding and sheker anymore and you want to be open with her. This way, you will be able to stay strong and recover fully. Tell her that ultimately this will take your relationship to a new level. Elya says not to say "I love you" too much, but I
do think that saying it can help sometimes. Every woman is different. Make sure she understands that the women you used to fantasies about meant NOTHING to you, and it was an addiction, an illness. Explain this again and again. She might not accept it at first, but it will sink in.
See
this page as well, and maybe have your wife see the links on that page.
By putting in filters on both your computers, and by revealing this to your wife - you have shown Hashem that you are ready to accept pain and go the extra mile to win this struggle. I am confident that you will see much siyata dishmaya in this merit. And we are all with you here. May Hashem give you strength to go Me'chayil el Choyil!
