Why do we encourage and justify these behavior/ACTIONS from women?

Following behavioral traits I've seen people on GAG say it's ok women to do it because it's biology or it's ok to do because it's woman thing.

Behavioral traits people SAY WOMEN ARE JUSTIFIED IN DOING:

1) Dropping their partner no matter how much, time, energy, money, emotion they've invested in them at the drop of a hat for someone else they perceive as better who has signaled they want a relationship with them. This to me shows no loyalty on the part of women and trying to justify this behavior is ok falls along the same line as justifying that a man can drop his 30+ year old GF/Wife to get with a girl in her 20's whenever he wants because after all she's better able to have kids and biology speaking men want a mate with the ability to produce many, healthy kids. However, of course in our society we would call such a man an asshole and shame him.

2) Women need to be provided for. I hear a double standard echoing that women need to be provided for as to why women date older men, date rich men, why women only date men who make more money than them. However, this to me just promotes laziness. Women needed to be provided for in the past because they had no access to education, jobs and relied on men to bring home salary to support them. However, women are more than capable of making their own money and supporting themselves so why is it we still justify the double standards.

We would call a man expecting a woman to cook and clean for him as a prerequisite for relationship sexist but woman wanting a man to still be breadwinner is not apparently.

3) Many young girls disregard men their own age to go for older men who can provide them with a lavish lifestyle while the men in their age group don't have much money. Some are successful in getting a ring, others are kicked to the curb for younger models. As these women approach 30 and the men their age are now in a position they want them in, they shame them for dating younger women.
