they reach their bottom patience. She hasn't reach it yet. No matter what you do or what say, she won't change because she feels hasn't suffered enough. She is a complaining person, in other words, she's a drama collector.
Drama collectors are not interested in living life as normal but complaining all the time. They need drama to able to live. If something doesn't have drama they are not interested. They look out for drama in everything out there own life.
So my recommendation is that stop worrying about someone that is not prepared to change. She will when she get tired of it. It's like a drug addict, they raise their hands when they touch that bottom....
