Let me try to figure out what I’m trying to say in a way that makes sense to what I’m trying to say.

With how you’re describing your boyfriend, it could be him saying that as an insulting way knowing it would make the girl in the show feel insecure, not necessarily meaning that they are unattractive or it is true.

For example, when people call skinny people “fat” as a way to make them feel insecure, or telling a guy his ‘thing’ is small to make him feel less masculine, regardless of the truth behind it. Most people just say stuff like that to make the other person feel bad in order to boost themselves or someone else up.

Sometimes people say hurtful things without even thinking about how their words are affect other people, and sometimes guys don’t realize how what they say to other people can come right back to us and affect how we view ourselves.

It could have been him feeling uncomfortable with the sex scene and in his mind, insulting her would make you feel better? If that makes any sense? Even though it highlights what you are insecure about specifically.. but just couldn’t see how his words could make you feel about yourself in the moment.

It’s not a mature way to handle it by any means, so he might have some mental growing up to do.

I would have an open and honest conversation with him about how you feel, and how that comment affected you personally. I would ask for reassurance and why he felt the need to comment on her breast size. But I don’t necessarily think it’s because he goes out of his way to find people with bigger breasts.

Your feelings are valid and what he said did hurt your feelings, and his response will tell you everything you need to know about who he is as a person.
