People are single nowadays because they were raised in a culture of narcissism. Marraige requires responsibility and sacrifice.
Your statement is very true. I speak from personal experience. I was committed to a 25 year marriage only to learn that my husbum was not. (PUN intended.)
He couldn't be bothered with things like loyalty and fidelity. He had an affair while I was dealing with our only son's life threatening injuries and nine surgeries.
He is not the first man to hide from a crisis by having an affair and he certainly will not be the last. In this day and age any woman who choses to stay married to a cheater must have a death wish. Cheating can be life threatening with the diseases that are out there and divorce is the only viable alternative under these circumstances.
True, and true of both genders.
