Marriage, simply, is not for everybody. It may take getting into it to understand that. It took Whoopi 3 times to understand/accept that it was not for her. It took me once!
And you are soooo right, ATV, there IS something that changes.
And if you get in and find physical abuse, that is an immediate deal breaker. Quicker that Kim Kardashian's short duration, if you ask me; no apologies or explanations necessary.
