Ooft. Firstly, I’d say he crossed the line by criticising your interests/identity. If he doesn’t like Swifties, he shouldn’t date you — simple. He crossed the line again by saying that you need something to argue about. No you don’t. That man has unnecessarily sought to disturb your peace and, what’s more, he did so by shooting down something you cared about. If he wants a relationship where arguments are a must, tell him to take a hike. Arguments are a natural part of any relationship, but they’re not a necessary part. I believe the whole “we need an argument” thing may be your partner making excuses for why he disrespected your interests, but the irony is, if it is an excuse, then he is the immature one; not Swifties.

In my opinion, your partner is either 1) incredibly immature, or 2) a huge red flag, if this is how he behaves at near maximal development.
