Throughout Family Guy, Peter does many things that would make any normal person leave their spouse such as
- buying a farm without consulting the rest of the family
- joining a terrorist group
- buying a motorcycle
- etc.
A few times that this happens, Lois threatens or says that she will leave him if this happens again. And then it does happen again. So why doesn't she leave him?
I'm sure some people are going to say "She's a main character. She can't leave the show!" However, I believe that it could be an interesting episode where they get back together at the end or even the way to end the series.
Now if I can think of this, hasn't Seth? So is there a reason she hasn't divorced him yet, either as a plot point or simply from common sense?
