She's been dating a 62 old man for the past three years and her relationship with him has many pluses and is satisfied with ALMOST all aspects.
The wrinkle that has appeared recently is that she has a longtime platonic male friend who has invited her to go on a 17-day trip to Europe with him. Over the past 20 years, they have traveled together to different parts of the world.

When he first invited her, she turned him down because she could not afford it. He then offered to pay a substantial part of the trip, she accepted his offer, but not until she told "Ernest" about the trip.
"Ernest" is very bothered by the idea, feels excluded and claims she's a gold digger. She feels that his protest is not only late but unfair, and she doesn't plan to cancel the trip!
She wants to know if Margo thinks she's a fool to jeopardize her relationship with "Ernest."
IN MY OPINION:
It's pretty obvious to me that she should not go on this trip. I'm sure she would not like it if he went on a 17 day trip with a lady friend and did not invite her.
Ernest's mistake was that he put up with his lady friend going on those trips all these years. Looks like this trip will break the camel's back! Enough is enough.
If she goes aboard, she could wind up being a lonely broad!
