Not really wedding related, but certainly marriage related. I was listening to the Dave Ramsey podcast this morning (don't judge lol) and a woman called in stating that she and her husband have been fighting their entire decade long marriage about caring for aging parents. In her family, parents put aside money for their long term care and do not expect their children to shoulder the burden. In his family, not only does the parent not put any money aside, but the children are expected to be the caregivers themselves without hiring help (or putting dad in a home).
The wife had established the boundary that she certainly could not care for her husband's father (he's in the military so the burden would fall on her) and with his father's health in decline they are putting money aside for his care, but it strains their ability to save for other things (like college for the kids).
Have you talked about what you will do for each others' parents?
