I need some advice. I am 29 yrs old and B"H i am very happily married with 2 children. My wife and I have a great relationship with great mutual respect. She does not suspect even a tiny bit that I have an issue with shmiras einyim. She thinks I'm this holy tzaddik. If she ever found out, she would be totally devastated.

We have 2 laptops with k9. My computer had VCF(which probably worked best for me) but since my computer is a small netbook the filter kept on giving me trouble and I had to switch back to k9. Unfortunately, the K9 on my computer does not seem to be doing the job and very often when I am home alone with my computer (and B'H thats not too often) I fall. My wife's computer is even less filtered with K9, but I still feel the pachad that she might find out what I did on her computer and I don't use her comp for bad stuff.

Is that pachad enough for me to ask her be my webchaver or is it still too risky?

Most of us here agree that making your wife your sobriety partner is not fair to her and not a good idea for a number of reasons.

Having said that, in my opinion, making her your web chaver is not making her your sobriety partner.
It does put a burden of checking the reports on her.
It also might present challenges, because sometimes 3rd party banner ads are actually placed there by other websites, and when that happens, a visit to that website is recorded. Even if you don't click through, it can be listed, and if it is a questionable site, it will show up on the list of questionable sites. So it's better to use someone who knows a little more about webchaver and what is and what is not a real problem.

A gut moed!

Personally, I would avoid having her be your Web Chaver. If you slip and give in (Chas V'Shalom) she will see what happened and it could seriously cause friction with your marriage. I tried to avoid it, but when I asked my Rav whether a chaver should be my webchaver, he said he'd do it for me. That was the last thing I wanted honestly, but it's a great impetus to stay clean and if I do slip, it won't ruin my marriage as my wife also is clueless about my issues.

Like Alex said, you need a webchaver who understands how it works and I would say one who would be dissappointed and can give you mussar and encouragement to stay clean but not ruin your marriage.
