If she is determined, there would be no point in arguing for or against it. But just like @mangaii had told she should also be working to pay some of her fees. She shouldn’t be expecting much. I read the guy is paying for other expenses and she too must be contributing for the shared costs. About your question whether they would work out or not, only time will tell. Nothing is predictable. I have seen married couples divorcing decades later in life when the kids enter college.
