Just to say that I don't regard my feelings for DH as "bullshit".
He lived alone before we married and was already an excellent cook, managed his home etc.
As two adults we have always shared domestic responsibilities. He did a huge amount when I was doing my Masters while also working FT - I couldn't have done it without him. He never once complained or begrudged a second of it - was supportive and encouraging all the way. When I had cancer, and depression afterwards - again, he was there for me. I didn't have to worry about anything around the house and even now when I am back to reasonable health, he's caring, considerate and pro-active in every aspect of household management. The only domestic chore he does not do (which is by mutual agreement) is the dusting, as he is asthmatic.
I have many friends who are single and live happy, fulfilled lives but that's not what this thread is about - it's about long term relationships without children.
I can't speak for all marriages but ours is very much a marriage of equals, and we are both in it because we love each other, not because of some heteronormative stuff.
And even if you are single, household management still has to be done. We didn't marry until I was in my thirties, and I left home at 19. For all that time, I still had to clean the loo, tax the car, change the bed, do the ironing, etc. Can't be doing with this ridicolous assumption that nobody single has any domestic responsibilities.
In fact, as a couple, it's generally easier and more efficient to get all the jobs done if you tackle it systematically.
