I honestly can't see any way they could--though at the same time I'm not sure where they go from here. I wasn't even sure last season when Sandra said she was moving out--is she taking Matthew? It makes no sense that she wouldn't, yet it doesn't seem like Matthew would know this guy, so maybe next season's about Stan being a somewhat single parent? That would be loads of trouble for Matthew if Stan approached that relationship the way he did his relationship with Sandra!

So yeah, the sad thing about their marriage is it doesn't seem like they're a relationship in trouble so much as two people who have become total strangers. So Sandra dealt with it by figuring out some things about who she was and deciding how her life should be. Stan continued trying to just define himself through his work at a time when that was guaranteed to leave him feeling more adrift.

But it might be nice if they could gain some better relationship just as co-parents. Poor Sandra tried as hard as she could as a wife and realized it was up to her to state the obvious about there not being anything there. How awkward to be living that way. It's funny how Philip and Elizabeth's fake marriage, by comparison, is so much less awkward--I'm talking about the flashbacks to their early life. Because back then it was awkward, but it was openly awkward. They both agreed that the marriage was a facade and they were actually kind of strangers.
