My boyfriend doesn't understand when I tell him his friend was rude?

I've been dating my boyfriend about 1.5 years. We do have an age difference (I'm 22 and he's 30). We met through work.

For some reason, his best friend Spencer doesn't seem to like me. I don't really like him either, but I try to be friendly. Spencer is a very outgoing guy, but I've noticed he likes to lie his way through life. Or he's aggressive and flips people off when driving.

We worked a catering job (as a side hustle) and Spencer was picking on me for no reason. Like telling me to sit on my boyfriend's lap loudly -- nobody laughed. In fact, it made my reputation ass. I told my boyfriend that I'm not cool with that. That if I did the same to Spencer and HIS girlfriend, that wouldn't go down.

My boyfriend just tells me to take a chill pill. Honestly he always NEVER takes my side, even when I'm right. Even in other situations.

I'm wondering if being quiet and not wanting to talk to his friends -- makes me the asshole here. I try to be friendly. But they just smoke weed and drink beers. It's not like his friends ever talk about hobbies or anything interesting.

Also my boyfriend sort of pushes me to interact with his friends. Even when I dont want to. Any advice?
