Like do they think mature means won’t pick a fight with them? Sure part of maturity means you won’t ~fight~ but rather have healthy disagreements where you state your opinion and 1: stand by it and successfully agree in the end, 2: stand by it and disagree, or 3: be swayed and change your opinion. I think they want an “agreeable” woman (or more than likely a pushover) rather than a mature one. The previous commenter said it best. They have to THINK to treat her right, and they don’t like that🙄
