I feel that marriage is more about social needs.

Today, a high school classmate messaged me to get together tomorrow. I'm glad I'm not back home; everyone is married and has kids. Most likely, they'll talk about their partners and children. Those who aren't married seem like outliers.
I probably won't attend these kinds of gatherings in the future. I used to think about immigrating because I felt that foreign countries are more accepting of unmarried individuals.
Do you all think I'm overthinking?😆
