In most cases it's women who seek out rich men because of the luxurious lifestyle a rich man can offer to a woman from an unaffluent background. Evidently, in this case it's the opposite, although he is richer than most but not as rich as her. maybe, he'll keep giving it up, hoping she'll pass on the next 5 years so he can secure the bag before she loses interest and dumps him.
I used to think he must be in it purely for the money, but I dunno, they've been together for a hot minute now. Plus she isn't your average old lady lol. I'd like to think what they have is real lol but that could be for my own peace of mind that when I'm 80 I can snag me a hot young American, minus the money lol.
