as for your last point about being able to get a hot girl - to me marriage has nothing to do with sex or getting a hot girl.
marriage is STRICTLY for children. there can not be any other reason to get married. if marriage helps you get more sex it is purely going to be sex with OTHER women who are into married men.
conservative pundits ( like the ones from Daily Wire ) like to bring up statistics that married men are happier and have more sex than men who aren't married. that is 100% true. but it has nothing to do with being married.
this is like saying there is more disease in Africa than Europe because Africans are not as widely vaccinated as Europeans. THIS IS LAUGHABLE.
the reason Europeans have less disease is because it's a more advanced society overall. Europeans wash their hands with anti-bacterial soap while Africans shit on the beach and rape goats to cure AIDS. it has nothing to do with vaccines.
same for marriage. the reason Married men are happier and have more sex is because successful men are happier and have more sex and women only marry successful men. then divorce the man if he stops being successful.
believing that marrying a woman will make you happier is like believing that playing basketball will make you taller. it is the exact opposite - you are signed by NBA *because* you are tall and you are seduced by women *because* you have your life in order.
no woman ever sees a junkie in a ditch and goes "he's cute, i will seduce him and make him my husband" - NO WOMAN EVER.
instead this is what women do:

pictured above is Harvey Weinstein with his wife. she knew he was the most notorious rapist in Hollywood, but also one of the richest and most powerful men in Hollywood as well and to a woman only the second part counts. she didn't care that he was literally the most disgusting creature in America both physically and in terms of his behavior ( serial rapist ). all a woman cares about in a man is STATUS.
and of course when Harvey went to prison she divorced him and is now dating Adrien Brody

she will claim of course she divorced Harvey because she "found out" about him being a serial rapist. but reality is of course everybody in Hollywood knew. she divorced Harvey because he lost his STATUS.
she was married to Harvey when his status as higher than her sexual market value. his status vanished when he went to prison so she simply replaced him.
as Mike Tyson said - women have no loyalty.
women are just using you until they find something better. my 1st GF said that to me in so many words - that she was just using me. she didn't say it to offend me - quite the opposite - she did it to save me. in fact at the BEGINNING of our relationship she made me promise that i didn't have feelings for her - i lied and said that i didn't. eventually she figured out that i lied because even though i never told her that i loved her she realized that i did. so she said POINT BLANK that she was just using me and started pressuring me to end the relationship, which ended about a month later or so because i was addicted to her and couldn't leave until she actually stopped putting out.
anyway, marriage is a tool that allows rich men to have children. if you're rich, want kids, and can get a hoe to sign a prenup and start popping out babies - do it. if not ? well, then you have to make your own decision - i won't make it for you.
