@futurebird I know three siblings in that age range, two of whom are in long term committed relationships, who have expressed a strict unwillingness to get married.
Why? Because their mom was awful and they saw what their dad had to get through in order to get away from her. Now they’re happy, the mom’s out of the picture, and the dad’s free. But it took decades.
I can see why kids witnessing people suffering broken marriages and messy divorces might sour on the idea of marriage.
