If marriage benefits men more than women, why are women always the ones pressuring their partner into marriage?

You always here how marriage benefits men more than women, and I'm not necessarily saying I don't believe that.

But if that's the case, I'm wondering why women are always the ones suggesting marriage to their boyfriends and quite often pressuring them into it?

I have a female friend who pressured (and bullied, tbh) her now-husband for years to marry her, and then acted surprised and giddy when he finally popped the question.

I've seen this dynamic play out more times than I can count amongst my peers (not always that extreme, usually more of a light nagging and frustration on the woman's part). Every single one of my close male friends felt some sort of pressure from their now-wives to get married.

It's been studied.

Usually, the women seem to want marriage more, and they want it sooner than their boyfriend.

There are entire subreddits, like "Waiting To Wed," specifically for women to bitch about their boyfriends not proposing. They are very active. No such online groups exist for men. Men are generally pretty happy to keep the relationship less formal and don't pressure women into escalating things.

So my question is why are men seemingly so unhurried/uninterested in this thing that benefits them so much? And why are women so much more urgently interested in this thing that benefits them less -- and is often spoken about as a major burden for them?
