"... HOWEVER... I also believe in LIVING-IN (for a certain period of time). You would only get to know someone during their unguarded situation. What if you got married to a drunkard, wife-beater (like my father used to be), a sex maniac ..."

Since when has a drunkard, a wife beater and a sex maniac all been classed in the same bad category?
