The dishwashing debate at home has intensified

My roommate has been saying for three days that the dishes are piling up and that it’s my fault. But honestly, I haven’t even cooked; I’ve just ordered takeout. I’m trying to explain it to her, but she’s not listening and keeps making snide remarks. Can you live in the same house with this much tension? Do you think it’s worth all this stress, or should I just give her a break?
