She disappeared without even telling him she was doing so. The fact she was carrying a human corpse from New Home>Core/Hotlands>Waterfall>Snowdin and finally back to Home should show this. NO ONE knows where she went. Even if she said she was disgusted, she clearly didn't put up much of a fight to change his mind. If anything, she sides with her son's murderer (albeit unknowingly). She's got some weird human fetish. Meanwhile, Asgore acts as Santa Claus for centuries, delivering everyone gifts, meaning he actually knows their names and existences and cares about each of them.

And clearly she knows this, too. It wasn't her place to fucking abandon her entire people to latch onto some human she barely knows (Sound familiar?)

tl;dr she should have tried a lot harder. Given him a clear ultimatum. But more importantly, why the FUCK wasn't she as angry as Asgore? Even Flowey is ashamed of her actions.
