So I went and stayed with my sister for 3 nights last week while DD stayed with Grandparents.
On the final day I cleaned her kitchen, baring in mind this is a houseshare so there was a few dishes and the tap was covered in black mouldy shit.
After finishing the kitchen I sat down with her and her housemate, I said just going to mention while I was cleaning there was a load of black gunk around your tap you just give it a wipe down, in her older sister we don't have a mother and I usually say things like this to her.
She fucking lashed out at me, saying I was rude, how dare I sit there and tell her to clean her home, how would I like it if she marched into mine and started telling me how to look after the place, I got up and walked out, upon doing so she laughed and shouted ITS FUCKING RUDE.
Honestly I was so embarrassed, felt humiliated and absolutely mortified that she said all this in front of her housemate. I got my bag and caught the next train without saying bye, it set my anxiety off terribly and all I wanted to do was get away from the situation.
When she realised I was gone she asked me to come back and she didn't mean to upset me but by this point I was so upset and my anxiety was through the roof I just wanted to get home.
We didn't speak until today of which I asked if she was still coming for Xmas, this then turned into yet another argument in which she told me I was rude, self righteous and childish.
I have now told her to leave it this Christmas, and I'll speak to her in the new year.
Was I completely in the wrong here?
We also fell out last Christmas, she's really narcissistic but can't see her faults in anything. She got a speeding fine the other week and denied all responsibility!!
