Okay I'm gonna do them one at a time but here's the 'William and Henry both went through messy divorces in the 70s' lore.
Will met his wife (Maggie Schmidt) outside a bunch of clubs in the 60s (they both smoke a lot). They hung out and hooked up a couple times and Maggie ended up getting pregnant. Since it was the 60s and also Utah they had to get married cus of this. While Will's happy with what a nice, suburban family does for his image, and Maggie appreciates the finacial security; they both can't fucking stand each other. I think this is cus they are, ultimatly, very similar and this pisses them both off. They try to hold it together for a while for Mikey but all this really does is result in 2 more kids. Maggie eventually has enough of Bill and files for divorce. He's initially pretty reluctant but the way his community reacts to the news is to SHOWER him in sympathy (he's really into that) so he goes through with it and plays up how it's effecting him. The kid's stay with Maggie most of the time but Will has them for the weekends (he also refuses to pay his child support). They're seperated fully come like 1982. They're both happier for it even if Will pretends it's a sore subject.
Henry and his wife (Eryk Maya) got married because all their friends were getting married and they got along pretty well (they were in the same Uni circles and were generally nice to each other). They really really don't click as a married couple though. Henry's really distant, aloof, cares more about machines than his human family; Eryk really doesn't understand this and isn't getting given the affection and support she needs. They divorce pretty amicably there's not really any hard feelings between them- they split a little sooner around 1978. Eryk takes Sammy and Henry keeps Charlie with him. He really doesn't handle the situation very well, he gets very in his own head about not being able to fulfil the nuclear-family-husband role as well as Will (apparently) can. Eryk starts dating his sister and also Maggie but Henry is completely oblivious to this (even when he starts living with them in the 2000s).
