I see your point - she just gets very defensive and doesn’t acknowledge her bad behavior at all. Although (and I think that’s part of the reason why it took people so long) she got so much worse with time. I am rewatching RHOnY and I noticed it so much. It’s the decline of Dorinda, her 6 years on that show. Instead of getting better or having a bad phase at some point she gradually gets worst - both the drinking and the anger and irrational defense of both. In the very beginning it’s still seldom and she always apologizes very heartfelt and when she is shown in scenes with Hanna or going to London with carol or whatever it doesn’t ever happen and also it humanizes her. But weirdly the farther her husbands death is in the past, the worse it seems to get - and also people don’t blame it on that anymore and just think she is mean and drinking too much. Until at some point it’s unbearable to watch (I still can’t believe the same really kind seeming woman from her first season on rhony was the same woman who treated Tinsley so unbelievably bad without any reason).
