You sound like a smart lady. Unfortunately, as an old goat, I must say that I have seen more than a few men AND women, intentionally and successfully hide an ugly and destructive aspect of themselves until after the wedding.
Actually, I do have a rule to address that: If one of you wants to rush the wedding... tough cookies. I have yet to meet someone who can hold it together for 6 full months without "warning signs".
But *way* too often the other party ignores these warning signs because their heart was already too invested. If you find yourself making excuses for your future mate or covering up their behavior, you're with the wrong person and (on some level) you do know that.
Again, you have to be honest with yourself.
