I think that this is an important message for the betrayed to know as well. I already feel like I didn't do enough or somehow he just wasn't satisfied with me. And I am not perfect and I never will be, so for him to forgive me for not being perfect, is just a realization that I am human and not infallible. It is a realization that he loves me and wants to be with me just as I am, flaws and all. Isn't that what love is, it says, "I have seen the ugly parts of you and I am staying." It might not be an accurate assumption, but that is the way that I am feeling about it. And it isn't saying that I am responsible for the affair in any shape or form, but that our marriage wasn't perfect and I did contribute to that.
