BOYFRIEND IS RUDE AF😡🤬

So this is me probably overreacting cause my birth control is making me hormonal and shit but I was just on the phone with my boyfriend, and by the way we aren’t like young teens but I may sound like one. His family doesn’t like me for weird ass reasons and so we were just talking on the phone, and his brother and female best friend just walked in and rudely started a conversation with my boyfriend. And I mean my boyfriend deadass didn’t say anything to me and just talked to them while I sat there and was forced to listened. This probably went on for like over 30 minutes. I find this so rude. am I just overreacting? I just got so fed up after a while and told him I was leaving and just hung up.
