“Fear of missing out” is used to explain why people use social media items they don’t need nor want. But marriage is an example too.
I know there is wholesome cases where people want to start a family with other people they like to spend time with.
But a lot of the times it was also “Hey I am of the age my siblings and friends got married. I should meet people with the sole goal of marrying them and raising children.”
I didn’t marry my ex, 4 kids, over 20 years, we were a family. There should be (there were for us) forms you can fill out to give each other access for medical information and also to set each other as the responsible party if you are incapable. You don’t have to be married. We had to get something notarized, that was all. Find out if you can do that where you are.
