( read details please) is it ok to do whatever just because " i was upset"

Ok, so everytime i try and talk about things going on, im attacking them even if i am literally showing them their own quote back, and trying to explain how cirtian actions im not ok with. They respond be saying im yelling and attacking them and that anything they did even if it was defiantly not ok, should be forgiving because " well i was upset what do you want"
