Life is like a book, each new chapter one could say starts at a new number say 10, 20 and so on. As you reach 40+ the pages appear to move quickly, even faster than before.
So to stop and assess along the way is good, if you feel you don't need to marry, why marry? If you feel you wish to live on the wild side and do free climbing up mountains, go for it.
Life is definitely too short to overthink the expected norms, enjoy doing what makes you happy @enazwahsdarb
