Well she also seemingly limited her own contact with people too. Like you didn’t see/hear a ton about her family until now. And other than Joe, didn’t see her interact with many friends either. With her now having days without kids she sees people now, and seems to have more help with kids from her family than in the past.
Just overall seemed to be a lot of isolation of the “family unit”. And even though she was also isolated, I still bet it was her doing it all. Especially knowing that even deep in the GS days Gaz was always about his family, so can’t see him ever being the one to make that choice.
