I’m not against people having whatever kind of marriages they like if all consent. But not sure why you would jump to that conclusion?
It seems she and her husband both lived in Texas. They had a vacation home in Mass, and she happened to be up there on Super Bowl weekend. Her kids seem to be in college in various northeastern states. From what I could gather her husband has a very prestigious medical job as a Radiologist at the Children’s Hospital in Houston. They also seem to have decent amount of money. Maybe she likes to travel but he isn’t always available and if money isn’t really an issue she might enjoy taking trips on her own.
I’ve heard that she and her husband might be separated but haven’t seen any confirmation on that at all. So maybe they just enjoy their freedom without having an open relationship.
fwiw I owned my own business for years and my husband worked standard hours, I traveled a lot for pleasure without him because I had flexibility that he didn’t.
