Elsa is the reason my boyfriend threatened to dump me

His favorite disney princess is Elsa. Mine is Ariel. So he said "Ariel sucks, she is no Elsa", I argued that Ariel is hot, he argued back that Elsa is hotter. I played all cool and said "oh, so I should be Elsa, then?", he said no, and I asked why. And then he threatened me with dumping me. <br><br>Why would he no longer love me if I become his dream girl, I don't get it
