Okay, so they're married, got parental permission, whatever. Here's the question that's really bothering me: how did they get to this point? Presumably before they got married they had to be dating, right? And if she's living at home, maybe getting picked up from there for dates, her parents had to know she was dating a 50+ year old man long before they were "really in love" or before they knew he was the "nicest guy ever" or whatever the quotes are.
What kind of parents let that happen? How do you let something like this go on long enough to get to the point where you're comfortable with them getting married, even barring how fucked up that approval is? I just...either they're horrible, horrible parents or they knew beforehand that he had money and put that ahead of their daughter's well-being.
...wait. I guess they're terrible parents either way.
