WHAT DO I DO?

i’ve been with my boyfriend for eight months. his brother is awful. his brother called me a bitch last week (and still hasn’t apologized), and then today his brother called me a trick and said as far as he’s concerned i’m the side not the main. And my boyfriend didn’t say hey stop or anything to his brother. After that call i said you can’t let your brother talk to me that way. He said i didn’t let him talk to you that way; he has his own voice. i argued that yes you did bc you didn’t tell him that was okay. And he said something like you were talking back to him after that. and i told him if you won’t stand up for me i have to stand up for myself.

What are your opinions?
