Shalom my dearest chaver,
I had a similar problem and I told her the story of Reb Amram chasida in the gemarrah wHere the holy sage reb amram who the ohr hachaim hakadosh calls the rabbis of all pious in other words he was the chief of them all and yet when confronted by an overpowering lust he almost succumbed (I think I may have read the story from inside the gemarrah at the shabbos table) in any event, I said to her "I don't trust myself, I'm only flesh and blood" I also added that a person who thinks that he ca be smarter then sages is doomed to fail. I told her that I'm not embarrassed to admit that even the big tzadik that I am is not allowed to be myached with arroyos (nothing embarrassing about that, Moshe Rabienu and the Chofets chaim were pretty big tzadikim and yet even they were not allowed to be left alone secluded with arroyos. Many times I repeated to her that un filtered internet is like an "erveh" and yes I don't trust myself.
After a few of these discussions, when my ears heard what mouth was saying, I said to her "sweetheart I'm going to ask you to put in a password in the filter and if I ever ask you for it (its a sophisticated fir wall that sometimes I need to adjust for legitimate purposes) promise me that you will change it within the hour".
I also taught her how to make sure that the filter is set properly to block all the bypass shenanigans that I had used in the past
.
Does my wife suspect that I may have stumbled in the past? Could be!! The wives are usually a lot smarter then we think! I know that mine is a lot smarter the me, yet she is also smart enough not let me know that she is smarter then me!!
She hasn't said anything outright to me, and for this I'm very greatfull to her. If she suspected anything then she left me a "fig leaf" to hide behind
Either way it doesent matter to me now! I think She respects me more for this!
My dear ninety, I guarantee u if u do it the way the guys on the forum are suggesting, only good can and will come out of it.
A note of caution, be prepared that if your wife does confront you point blank, it may not be the smartest thing to tell her the truth! She probably will not be able to handle it and its no sin to just say "I don't want the temptation period".
The old "dicretion is the better part of valor"
You may want to consider saying to her that you just
realized that this a halachic question that we need to ask a Rabbi/Rov not any less in importance then any other shailos in laws of yichud.
Please keep us posted, we are all with you in our joint struggle!
With eternal love
Noorah BAmram
