Idk man, most of the time a female says 'I love you' to me first, but I don't really base my relationships on strict gender norms like that or something. I also wouldn't waste my time on a woman that was clearly looking down on me and making me go through hoops. I also don't care if I'm 'gay', I'm straight enough to know better anyway put it that way. lol.
I do see a lot of beta males that are getting 'chumped' in love but I think this sort of thing comes from overly idealizing women, it is a kind of reverse misogny- instead of seeing a complicated person with a mixture of good/bad flaws you see the beta male pov that 'women are these damsel in distress that need me to save them.' Even Britney Spears tries to tell Beta Males 'You must think that I'm sent from above, I'm not that innocent' lol
Women are often wiser to know love is a rare special gift you shouldn't give it away too easily. 'I love you' should be meaningful and special. And it is special between two people, nothing to do with 'society' but a "Beta Male" is often focusing too much on the society thing.
Females have less empathy than males period, but better compassion ime. Of course some females are just pure narcissistic sadistic bitches just like some males are pure hateful assholes with no heart whatsoever. Not really a gender thing. This isn't exactly news at 11, but just putting it out there for our general humanitarian ness or something I guess.
If somebody doesn't like you (male or female) they will have a dark, twisted kind of cognitive-only empathy with you, where they will kind of one-sidedly absorb certain 'dark' or negative qualities in your psyche logically (in order to best try to trap you with), but never relate to you in an affective way. This isn't really a gender thing to me tho I mean you see a lot of people do it... maybe it's a Gamma Quadra thing to me in a sense, or Se in general? Gammas can be brutally cold and harsh this way at times, but they do have SEE/some ESIs softening them up at times lol.
