Though I have to say, even things that are "script" aren't BS to the person saying them. I think that when a WAS says things like "I don't love you anymore," or "this will never work," etc., they really do think that. Now, maybe they only think that because they have convinced themselves of that so that they can justify what they are doing in their own head, but regardless, I think they do actually think it.
...or are trying to convince themselves that's the truth because they are so hurt.
You could have asked me on any given day during my M before BD, 'do you love your H?' and some days I might have answered, not today, ask me tomorrow. Marriage is a fragile thing and once the momentum starts to go south, the trouble snowballs, especially if the love bank is already near empty.
Caveat, some people do lie, just because that's who they are, but I would guess a spouse would know if they were married to a person who doesn't tell the truth.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
