Is he ok with me claiming him?

I told my friend that the guy I’m dating is my boyfriend. Long story short she met him and told him that I said he was my boyfriend. His response “she can say whatever she wants to say. I’m her best friend, I’m in her life. She can say I’m her husband I really don’t care. “ Does his response seem like he was upset. Or he doesn’t mind me calling him my boyfriend.
