It's been a very long, long time since I've seen Fatal Attraction. 1987 is a year that grown folks behaved innocently when they were not.
The man got away with cheating on his wife and child -- his family for another woman who was played as a possessive lunatic. The woman claims pregnancy and is obsessed with him.
The man feels like he can do this get away with cheating dance. But showing how some women are wacky.
I don't like to call other women crazy about dick, but that's what this is. His dick is priceless, while her "fuck" was made worthless, made crazy and withers on the vine because she died.
But there were 1987 scenes that gave scenario questions.
A man cheating on his wife and child -- his family -- with pussy thrown his way because he's weak. Seriously, a man meets a woman at an event/location, becomes horny for her and they have buckwild sex. Back in 1987, sexploration wasn't acceptable. Being single and fucking wasn't acceptable. People were supposed to get married young, have children, buy a home and live happily ever after. When a husband alleges he's bored with the monotony of the marriage, he cheats. He's at the peak of his prime at that time.
A career woman, who doesn't have a mate, and likes fucking men, wants a relationship, but can't find one, etc. She's nothing and thrown away no matter how insane it makes her on that double-standard. Today, it has started to change. Most young women ~30-something have said they will find their relationships where they are. Some have chosen to enjoy same-sex relationships. Some pursue polyamory. Some enjoy other arrangements. Some are ACE/ARO. That's an advance. A big one since 1987.
Some men are roughly at a similar level. But some macho men are INCELS that want to be the wingman role that get the off pussy shit "JIMMY" since they can't be "DAN GALLAGER" since these men cannot handle a wife and mistress. Of course they say, what the women look like.
