Why do people get married if they're not planning to have kids?

If they're not planning to have kids, they can just date. Why do they get married if they eventually would divorce, making themselves divorcees?

There are two couples I know that got divorce easily. They told me they got married for nothing.

There are a lot of people I know that got married but have no plans to have kids. What do you think is the biggest reason they have to get married then?

'Do you have kids?'

'No, I don't have any plans to have kids'

'This is the reason why our country has low birth rate'

'What year is it now? Why do you still talk like that!'

'I mean, it's not like I have kids to increase the rate of this country's birth rate'

'Let's listen to Kim Eana's explanations'

'As a couple, maybe we will never experience the happiness of having kids'

'But on the contrary, those couples (who have kids) will never experience the pleasure of living together with your partner without any kids'

'How long have you been married?' '12 years'

-I don't have any plans to get married. But if I ever get married, I'm planning to have no kids in the future.

-Because we don't get married just to have kids. We get married with the hope that we could live the rest of our life with that person. There are also people who get married for their safety or validation from society. For the latter one, if they ever have kids, the kids will only be viewed as a tool to them and I really don't like the thought of that.

-If I ever get married, I would save our money and use it to travel across the world with my partner. Maybe we would try out great hotels, great foods, etc. I just want to create beautiful memories with my partner. Besides, I don't have any money to raise a kid.

-Because people don't get married just to have kids. They just want to spend the rest of their life with someone they love.

-Honestly, I can relate to her at some point. I don't have any plans to have kids, I don't want to get married. I just want to date and spend my life with the person I love. However, I'm starting to think to get married just to avoid this judgement.

-Because until they actually get married, they think they would have a great and happy marriage
