Uhhhhh y’all I never post but wtf

Sooooo just a little background, my boyfriend is a white man I’m black most of his siblings date interracial as well. Anyway my BF surprised me with an Airbnb gettaway for my birthday this week so we’re on this cute little island that his step mom happens to live on unrelated to why we came but I said hey why don’t we at least stop by her house(I’ve met her once she seemed nice). Fast forward to our first night we go over for dinner she pouring me wine glasses after wine glass. We (bf,dad,stepmom) start playing a board game we’re all chatting having fun and then...... her drunk ass says you know Jason (my bfs brother in law who’s black) let’s me say NIGGA AND SHE THEN SAYS IT AGAIN!!!! I was in complete shock! I spazzed out and went to the bathroom my bf comes for me immediately and we left. I really feel like I want to go home and dump him 😞😭. I just can’t even.

Edit: HE DIDNT SAY ANYTHING. I said wow why would you ever think that was ok where do you get off saying that etc and he sat there quite and”shocked”. Yes he came to get me obviously he knew I wasn’t gonna want to hang out anymore. IM PROUD TO BE BLACK and my boyfriend knows that! I’m not shy about it because he’s white. If my family did something like this I would tell them about themselves! I love him and would tolerate my family saying dumb shut so why didn’t he say anything!? That’s why Idk about being with him!
