Nowadays they don't only expect you to be Chad facially and tall, but you also need to have the emotional intelligence of a psychologist and the personality of Harrison Ford (or whatever dude women describe as manly, funny, charming and NT), the lemon isn't worth the squeeze, the mental toll of trying to form relationship and open up, only for it end abruptly, again and again again, is Giga Brutal for some people, sometimes it's better to not have expectations at all, instead of having them get broken constantly.
You lose a part of yourself with every failed relationship. Its beyond brutal sharing your emotions and making lifelong memories with someone, only to have them disappear from your life before the year is over. It devalues your past and future experiences at the same time. You can't revisit certain places or activities because it reminds you of them. Every girl feels like a rebound that won't lead anywhere. After a while you just expect things to fall apart with everyone.
Indeed, for women it's just a fun game to see how close the man is to the fantasy she read in novels and watched in movies, they can easily replace you and jump to the next exciting experience or even just become alone, women can be single and not have sex for years, and they would still prefer it over being in a relationship with a man they don't see as "ideal", while for men, after a time with a woman your provider protector instincts start to kick in, and when you lose her, for your brain it's like you missed on your chance to reproduce, that's why heartbreak for man is so intense and they feel like they would do anything to fix it.
