Who not to marry...

Never marry a woman whose father took off or was abusive to her mother UNLESS she got the right lesson from it ... the right lesson being that responsible men are to be adored and valued and their eccentricities and (mild, occasional) irresponsibilities tolerated. You need to have clear evidence that she took the right lesson -- if not, you're going to have a nightmare marriage dominated by her suspicion, paranoia, and total inability to please.
