I'm screaming at Her relationship with Calvin lasting the full duration of Her tour, when She was probably much too busy to actually spend much time with him (despite his attendance at well over a dozen shows)... I can see why She would move on quickly if there was little substance to Her relationship with Calvin tbh.
We do not know the situation. She and Tom clearly clicked at the Met Gala where they were co-chairs. Calvin Harris had been distant and looked unhappy with Taylor for awhile. Tom was active with her, danced with her whereas Calvin Harris refused to even attend WITH her, any events really. There are no children involved and no marriages so I say there is nothing wrong with it. Let her have fun, people are going to always joke about her dating life and songwriting anyway so she may as well have fun in the process. Now the jokes can stop about Taylor being dumped, as it appears she might have dumped Calvin. Rightfully so, he look miserable with her and that had to be embarrassing for her.
Like I wonder how long many of the people judging her wait between relationships.This kinds of things happen in real life.
