On the flip side, if the genders were changed in this situation and the guy only wanted the woman because of superficial reasons like she was attractive or popular, how many people would be saying "he got what he deserves"
This is definitely one of those double standard situations. While we shouldn't be victim blaming, I think there's something to be said for calling out people who are willing to throw away an existing relationship or form a new relationship just because an "influencer" came up to them and they thought they were rich. And I think that's what the poster you are responding to was getting at.
