OK, I have a few more minutes now. Before anything else, it's important to realize that a lot (probably most) of the people here had similar questions to you when they came here, even if they don't pose them in the systematic way that you did. We feel strange being told we have a problem, certainly an "addiction." We can come up with all sorts of elaborate explanations of why we're NOT addicts. My personal approach was that it didn't matter - I had certain behaviors i wanted to stop, and using this approach would help me best. Eventually, I came to accept that my problem was probably something like an addiction. Especially when I realized that term "compulsion" definitely applied to what I was doing - we feel compelled to do something, and we certainly find it difficult to resit it!
Some people are more susceptible to becoming addicts than others. This is true of alcohol and any other drug, as well. Some people can use substances for a long time without it interfering with their lives, while other people's lives are extremely disrupted by it.
The term addiction has nothing to do with how many people are doing it - it has to do with whether or not it's interfering with your life, if it's out of control. If someone has an eating habit that he cannot control, that would be a problem, too. Most of us are able to push off eating, and eat in the amounts that are good for us. If we would be unable to control ourselves, there would be a problem. That's why overeater's anonymous exists.
SO the question is, is it interfering with your life in some way? Is this something you want to be part of your life, and are doing it because you're ok with it, or is it something you don't want to do, but can't stop?
As far as your kids, of course you can help them - the more emotionally healthy they are, the better off they'll be in every area, including this one.
As far as what hashem wants, I'm not sure what your question is. You have a desire for something that you're not allowed to do, so clearly, hashem wants you to grow past this. HOWEVER, I do not believe that hashem wants this to be so difficult for you. One of the things you'll hopefully discover is that the goal is not to constantly fight this urge. It's to live in a way that you don't have to fight it, you just live your life in the way you want.
6. It's mentioned in the handbook 2 things I want to challenge: 1. You should always prevent from looking on women. In my eyes, it's not just impossible, but also not what the Torah way is. "vloi susiree achrei..." doesn't necessarily mean "not looking". In fact, the Torah doesn't say "don't look" but rather "don't follow your look"! So, A. how am I suppose to watch my eyes?
Please re-read this sentence you wrote. I hope you can hear the rationalization there. When you're walking down the street, women are not invisible. Even the biggest tzadik doesn't bump into women because he doesn't see them. But he doesn't keep looking at them. I can walk onto a bus full of women who are...wearing less than they should. I notice this, and I then
choose not to look at them. This is aided by reminding myself that they have nothing to do with me.
I know I didn't address all of your questions - some of your questions I'm not exactly sure what you mean, or I'm not sure of the best way to answer them. I hope this helps a bit, though. How are you doing?
