Is it rude to flirt with other guys in front of crush?

Anonymous
When I'm around guys, I can't help but flirt with them. There's one guy I really really really like. We sit next to each other, follows me on social media, likes my posts,
He introduces me to many of his friends and im too flirty with them that he dislikes introducing me to them cause he knows I might flirt with them. When I flirt with them, he looks away and looks uncomfortable.
He used to flirt with other girls in front of me when we met but he stopped.
