Men and women approach marriage very differently
I once had a talk with an (ex) male friend after my breakup. During that chat, I told him I was childfree, and he responded by saying "what's the point of wanting a marriage if you don't want kids"?
My response to him at the time was more from a legal perspective. I discussed hospital visitation rights, medical decision-making authority, inheritance rights, and veteran survivor benefits etc. Basically everything that gay couples fight for.
It only occurred to me now that most men wanted marriage for very different reasons. I approach marriage thinking of "how we can take care of each other when we need it". But he approaches it thinking "free unlimited sex and making babies".
Anyway, we're no longer friends because he made me uncomfortable more than once. He's one of those guys who broke up with his gf because she wouldn't have sex with him. I severed ties with his friend group too, because they had proven to me that birds of a feather flock together.
Funnily, now I totally agree with that ex-friend for very different reasons. Why the heck do I need to get married? If I am financially independent, there is literally no need to put myself through the ordeal by marrying a man and dealing with the legal issues (+time, money, mental health) if that marriage falls apart.
