Not sure whether Bethesda will comply with the fans' demands...the inability to marry her is not due to oversight or bugs, but rather her character and the insecurities she carries around. Somehow the idea that she'd reject a marriage proposal didn't strike me as OOC - she
is carrying quite a heavy internal burden,
I know many will disagree with me, but I don't mind not being able to marry her - especially if this ability comes at the cost of character consistency.
