My brothers gf is Chinese and they've "disowned" me because they say I am racist. Now believe me or not I am not racist. My crime is that I dislike her, regardless of race. I find her rude (she had a fight with my brother at a family lunch and I tried to intervene and tell them to leave and she threw her drink over me), we disagree about a lot of things and are just so so different. For example, we go away to Hawaii a lot ( twice a year pre COVID) and she always makes snarky comments as I think she's jealous we can lead that sort of lifestyle. We are childfree and both professionals. Anyway, since they both (inc my brother) accused me of being racist I am done with them. I am happy to have been blocked and disowned. My mom is now trying to be peacemaker etc but I just said sorry we will see mum separately to them and I think that will work.
Am I being Aibu?
