29 is little old to be playing that card. At that age you could equally argue that she's the one being weird in this scenario.
older rich men get preyed upon by younger woman sometimes too.
That's why the energy is different when you are related to the older guy in these scenarios. When a 29 year tries to claim a piece of your inheritance, you don't act like dad is weird. You act like his young wife is a gold digger.
