I also have a friend whose mother I know well. The mother had an affair and I have spoken to her about it and the reasons why. Her H used to drink a lot and they didn't do things together, he wasn't listening to her as he basically became an alcoholic. When she had the affair, and it all came out, he stopped drinking cold turkey, never touched another drop, she told me even if he was carrying drinks and some split on his hands he wouldn't even lick it off... They recovered and had a much better relationship going forward until unfortunately he died from cancer last year. Something that affected me a lot last year as I was close to them as a family for several years.
