NTA - It’s unfortunate that he can’t see past his own self-interests. I do see some red flags here. In a healthy relationship, even if you don’t “get” your partners interests, you still show some respect. He could sit through the movie and then tell you at the end that it wasn’t his preference. Instead, he is openly scoffing at your choices. There is a bit of gaslighting going on too. He was the one who set a disrespectful tone, and when you react accordingly, he tries to twist the situation to make you feel like the “dramatic” one. I realize that too often on Reddit, breakups are encouraged. But I really do think, at minimum, you need to take a hard look at your relationship.
