Glad you changed your name but I would think about changing it again. We do not look for control here, only sanity.
You ask why a filter? You say MY WIFE WILL FIGURE OUT I HAVE AN ISSUE AND THEN WHO KNOWs WHAT SHE WILL DO!!!
We say: chill out. I also thought that if I mentioned the word 'filter' EVERYONE will know I struggle (by the way, who is 'everyone' that we are always afraid of?) Guess what I brought up the 'F' word and lived to tell the tale.
See, part of this addiction thing is that we have a very funny perception of the world. One place it comes out is in "FILTER" and other safe guards.
Blame the filter on your Rabbi. If he does not think you need a filter GET A NEW RABBI!!!
Also the was a very interesting article about the internet in Mishpacha Magazine this week. Get it show it to your wife.
You ask if I get I filter that will solve my problem?
I say: If that is true so why not get 100 of them? Do you like 'living' like this?
I also say: the real answer is that YOU ARE WRONG!!!!!!
Lust addiction is not AT ALL about the urge to lust.
It is about you or me trying to hide from our feelings. We have feelings we are trying to hide from, that we are afraid of, that we are petrified of, so we look for something to hide in. Some hide in drugs, some in food, some in alcohol. We happened to find lust first.
You and I need a filter so we can stop lusting and listen to ourselves and learn what we are trying to hide from. Once we figure it out we can start to work on it.
I suggest you get a good book on self esteem for starters. You should also think about learning Ali Shur from Rav Wolbe or something similar.
BEST OF LUCK and keep on trucking and posting.
