I created a new account in case this gets indexed somewhere. I am in my 30s and my own parents are still married, but they should have gotten divorced a long time ago. They never did, "because of the kids" and it pains me. They are fucking miserable. I have not seen them lovingly kiss each other in at least 3 decades (I only remember once when I was a toddler). They do not have intercourse of any kind, sleep in separate bedrooms, fight constantly, my dad has been having affairs (unsure if my mom knows about them, I doubt it would change anything if she did), all because they are too ashamed to get divorced, and at this point, they're too old to do it.
Of course looking in from the outside they seem like a happy couple - always went to social functions together, etc. But on the inside, definitely not. I always wonder once you take out the marriages that end in divorce, how many of the ones left are like my parents - happy on the outside, fucking miserable on the inside. In my own experience, the vast majority of friends' parents have been divorced, sometimes multiple times, and I already have friends my age who were married and divorced.
Needless to say, I am in no rush to get married, even in my 30s. I do have relationships when it's right, but I don't let society tell me if or when I should be getting married, if ever. It's way too big a risk to my personal happiness.
