I actually disagree, so I've been with my husband 19 years, we've been through the thick and thin of life together and he's a pretty amazing person. He's kind and funny and sexy and amazing in bed and does his share of drudgery.
However 'romantic' rekatio ships are taxing, you have to learn to live together, to forgive each others foibles, to treat each other as resources for the home and childcare and to work out how to manage joining finances.
Every mistake either of you make effects both of you, every victory is shared etc etc but the level of vulnerability needed when you know about each other's every embarrassing moment from parking tickets to haemorrhoids is an awful lot to weather and goes well beyond 'ramance'.
My marriage makes my life infinitely better but it's a knife edge becauE when I was single and every man for themselves you have a freedom to make mistakes etc that only impact you.
Anyway what I really wanted to comment on was the other relationships in our lives and I think those can be as central and meaningful as a standard monogamous relationship. I've one single, child free sister and she has the deepest and kindest friendships I've ever seen. She is loyal and shows up for people a s consequently people show up for her.
Just because you (and I) find our fulfillment in that one on one traditional marriage type relationship in no way dictates that others must do the same.
