Cooper family dynamics
Isn't it true that whereas Mary struggles to see the perspectives of her children, Georgie's version of being responsible also subjects the women in her life to a version of "protection" that is too simplistic and controlling? Whenever Mary or Mandy do stuff that he has reasons (often good ones) to be against, instead of listening he always takes it as a personal offense and tries to control them.
I say this not to bash Georgie, who we all agree is doing his best as a young man forced to grow up quickly, but to say this is simply what family do for and to each other. Sidenote, it seems like a theme that Mary often makes questionable choices when it comes to her love interests: George Sr. (who Meemaw was initially against), Pastor Rob, Leonard's Dad in TBBT and now potentially Fagenbacher.
