Well I am 50 and just got married second time. Society doesn't give a damn if we are married. My family can't care less about legal marriage especially if no kids involved. I have been in a long term cohabitating relationship with someone for almost 9 years. Clearly society did not pressure me to do anything. I dated other people etc

Then I met my second husband and we are just a great match and wanted to be married, we are happy and we like being by married. There might be was some societal pressure in old times especially if you want kids but those times are over in the western world. If one doesn't want to be married they don't have to be
