1.Keyloggers are not illegal on your own computer.
2.This board is for people who DO have a problem with porn. There are millions of people who have a problem with it. If you don't have a problem with it, you're on the wrong board. If you're going to support people who are struggling, great. Otherwise, don't belittle people and what they are going through.
3. Only someone who is defending porn would say something like, "you reap what you sow". She needs to take control of the situation, and her life. Ultimately, that can never backfire, only empower. Anyone who would fault someone for standing up for themselves is only out to further their own cause or protect their own selfish behaviors. Since her h chooses to lie, and cannot put his wife's needs before his own wants, it is up to her to take care of, and protect, herself. Since nothing of truth will come from the horses mouth, you look elsewhere on your own. If he doesn't like it, he is always free to grow up and make different choices.
