There is an epidemic of women like your mother in law and rather than take responsibility they have found ways to twist it into somehow being men's fault. Women don't take responsibility for their own happiness and constantly leave it on someone else's doorstep. That leaves them miserable and continually unhappy. Never having had to really do anything themselves, they don't even know how to make themselves happy.

So they find pleasure in quick boosts of dopamine- social media, alcohol, pills, etc. This leaves them worse off and unable to handle their situation so they need more dopamine boosts to offset it, that leaves them even worse than before...and they keep cycling down. This has been going on for years and so many of them are beyond help now.

Why do you think there has been such a push to shame and degrade men? They need someone to blame for their misery. This, of course, makes men more likely to say fuck it and just not participate at all. This increases women's misery and increases the 'why are there no dateable men around?' articles that only makes them more unhappy but at least it makes them feel like it's not their fault
