I think the hardest part for my daughter (as she certainly has known she'd have to get to that point)...is it sounds like her fiance's parents intend to pay for phone, insurance, school, etc at least through graduation...who knows maybe longer...
I did tell her that thanks to new health care laws she can stay on my benefits until the age of 26 whether she is married or not. But I think she'll also probably be surprised when I remind her that that doesn't also mean that I'm willing to pay all the co-pays or additional amounts that insurance doesn't cover...
And that part is not poor parenting - that is just me being poor...
