I doubt it's because she fancies him. Wonder who she forces herself to think about when sleeping with him.

Would you really want to marry someone who is probably just pretending to get hands on money.
Someone who looks like that and is so much older but is rich will never know how repulsed someone might be when sleeping with them. Would that not bother you?
How long before they'll be divorcing and she get a nice pay out.
