I have no interested in marriage and I find the concept absolutely bonkers. I shouldn't be financially and legally bound to someone to be their romantic partner. Been with my SO 16 years and we have a home, absolutely not interested in having kids and have never had any reason for marriage.

And if he ever has any medical or other kind of debt I won't be responsible for it. I won't be responsible for his funerary expenses etc and vice versa. I should not be responsible for someone I didn't birth. He's been there while I recovered from surgery at the hospital. Being married does nothing. He is listed as the one getting my life insurance and will get my savings if something happened to me. No kids, no exes, nobody to try and contest it. And if something changed I don't have to worry about 'divorce' and all that bullshit. What's mine is mine, what's his is his. He can use my debit card if he wants and I can cut access with a press of a button if we somehow broke up, which won't happen but still, it would be a clean break unlike married couples. Marriage is pointless.
