I think it's emblematic of Toriel's general disconnect with her child.
Kris is currently living an entirely different life from the one Toriel thinks they're living. One part due to the dark worlds but another part due to the way Toriel's divorce negatively affected them more than it did for her.
She doesn't really accept Kris's true feelings on the divorce, thinking the decision was better for the family and therefore automatically better for Kris.
It's a problem a lot of divorced parents go through; where even if it's the objectively good decision, they don't wanna accept that it's valid for their kids to feel negative emotions about it. They think that they can brush it off and eventually the kid will come around to the new situation. It's a really shitty way to handle it because as a parent you're just thinking about yourself but not how the kid feels.
Y'know how every Disney Channel movie about kids accepting their parents' divorce has them ENTHUSIASTICALLY support their parents and be happy about it at the end? That's not a message for the kids, it's faux reassurance for parents to make them think their child must definitely have the emotional fortitude to handle difficult situations like these.
That is to say, I don't hate Toriel, I think she's a well written messy fuck-up of a mother.
