What do you mean? I don't understand anything of what you are saying? What am I trying to take that isn't mine? (And why me, I am not the OP)?

What is a five finger discount?

Five finger discount is when you steal.

The condition of staying in good relations with your wife where she does not take the children and blast off is not having a romantic life on the side.

You understand this condition but try to get around it by lying. Not because it is unfair or impossible. Just because you want to have good things without paying for them.

So in your opinion, the punishment for having an affair should be to have one's children taken away from you? Or at least, you think it is an appropriate punishment. I don't think everybody would agree.

You thought all of that by yourself.

There are a lot of ways to breach a "contract" that is marriage, including a voluntary termination. However, being unfaithful is a good way to ruin your marriage, so if it means things to you please don't cheat your wife, unless explicitly being on different terms (and even then...).

This one is totally reasonable. It does not grant you any protection for the other cases, though.
