1000% you're correct, men have always love harder because that's meant literal work/providing/sacrifice as a minimum, in addition to validation and affection. To really make the cypher complete you'd ideally be able to be vulnerable with the woman but that's the catch-22. Woman don't like that shyt. They want to confide, cry to, be supported emotionally by, have tears and fears calmed by YOU, the man. Once you show chinks in your armor the dynamics often change and now she has the ammo she needs to shatter the mans heart and subsequently his mental. I know I have one actual love left in me, after that not a chance I'm as vulnerable, shyt I've had mild heartbreak and it makes you more precautious and hesitant to trust/open up. When I meet women I tell them tongue in cheek I'm boring and emotionally unavailable and that's the case for most women I'll come across because we won't have similar intellects/interests/taste, and I'm able to ID their surface level reason for interest because as aforementioned it's not me as a whole, it's my car, my physique, my humor.
People grossly understate how understanding people and having the ability to relate/connect to different people/be personable doesn't translate to you finding someone you have a genuine connection with, that goes for women, acquaintances, and associates
