I, 25F, have been dating my bf,26M, for 2 years. Last weekend, his cousin came over to help me with something. His cousin started talking to her friend on the phone on speaker and my bf joined the conversation. I asked his cousin if she wanted anything from McDonalds and the person on speaker started saying things like “is that a black person? I knew it” then precedes to call me a n word and a n word with the hard hard er. To my dismay both his cousin and my bf started laughing, i got upset and started crying and his only response was “I was half asleep, kids are going to say dumb things” AITAH if I breakup with him?
