Why did it offend me when my boyfriend said this?

So we were talking about my cousin who seems to switch jobs and apartments all the time and I was saying I couldn’t figure out why she isn’t stable. And he said, “it’s probably the ‘inner boss’ in her that causes it, basically complementing her and saying she has boss-like qualities. I don’t even know why it offended me the way it did. I don’t know if maybe it’s because he doesn’t ever uplift me in the same way or if he just doesn’t tell me the good he sees in me. But it really bothered me. Especially since I just graduated from nursing school and he barely told me he was proud of me or anything.

I don’t know. Am I just overthinking or what?

Please no mean comments… thank you.
