Is it just me who thinks this?

I really don't care what other people do or don't do.

Some people dislike children, and like being in a monogamous relationship, and their idea of perfect happiness is marriage or a long-term relationship without children.

If it doesn't appeal to you, great! You know what you want! Just don't marry someone who genuinely wants to be in a marriage without children, it wouldn't be fair to them.

sure, lots of points. companionship, intimacy, care-giving & care-taking, someone waiting for you when you come home, the occasional hot meal, travel companion, someone to talk about what you're reading/watching/thinking.

or so i hear...

they fall in love?

If that's what they want then why not? A lot of marriages don't work out (regardless of whether or not they have children) and people end up getting a divorce. Some do.

Also, marriage doesn't actually prevent or restrict people from having relationships outside of it...

The commitment that marriage represents legally, spiritually and socially help keep people together during the hard times, which most relationships have. It also demonstrates to everyone, your partner included, that you hope to be together forever. It also merges 2 families together, which tends to be a strength , which extends to the community. There is also the benefit of solidarity that it presents to children. I can't imagine choosing between 2 parents for my last name. Yeah, lots of good reasons to get married.

🤔...Cos they love each other maybe.

Companionship.
