Uhh.. Actually you shouldn't have commented on her message box like that.. I am neither supporting you nor her cuz I know it's irritating for the notifications to flood like that, same happened with me too even after I unfollowed her.. But what you said is quite not ok.. I mean we dont know what psychological problems she's facing... We don't know if she is really acting or not.. If she's acting, what you said doesn't really matters, but if she's not some times we may become one of the villains of her story.. These are not the words that meant to be rude.. I just want to tell some people can behave like that aggressively, we don't know their back story, like if sometimes if they are in too much in anger, they tend to loose their patience without analysing about what they are actually talking about..
Just leave it like that, I am not actually ok with the things she say to others, it's really rude for her to say the harsh comments to the readers even if they are not really rude about her.. So after few days i thought may be it's just her way of thinking, after reading many comments. But we don't know why her way of thinking is like that right..? Just leave her.. If she's really not ok in her life we should not add any fuel to the fire..
This comment is not really meant to be rude neither on her nor you.. It's just my opinion..hope you understand.
