Bf thinks my friend is more attractive

So my bf is out with his friends tonight and he sent me a picture with his best friend saying “we’re so hot.” This is really mean but his best friend is very unattractive. I texted back that his friend was more attractive obviously joking and it’s something that I’ve said jokingly many times in the past. So then he gets all upset and is like why would you say something like that? And then he tells me that one of my best friends is more attractive than me. But she’s actually gorgeous like everyone is obsessed with her. I’m like really upset now bc I feel like he thinks or wishes he could do better and he doesn’t actually think I’m attractive. I’m very insecure I used have problems with eating and I’ve gained weight since I’ve gotten to college which I’m really upset about so it’s just so hurtful that he would say something like that 😭😭😭 and now he’s drunk and super irrational and doesn’t understand why I’m upset or why anything is wrong
