well said. but it's still not anyone's position to tell her
whether it's possible to trust her hu*****and again.
she can respect herself and still choose to forgive. I know it's very difficult, but since i never had the experience, i can't say it can't be done. what you said was simply too absolute.
you seem to be overly idealistic about the hu*****and-wife relationship. as if it's so holy that it can't be wrong for a tiny bit... but life is long, and there're many chances to any relationship to go wrong. married couples have to learn to deal with problems, not simply quitting it when the perfection is broken.
it's nothing to do with self-respect, as long as both can face the issue and find a way to deal with it.
