She knows you CANNOT AFFORD to divorce her so she will use you to the fullest!!!! 
The other choice is QUIT YOUR JOB MICHAEL, I bet she will do a turn about face... 
Did you go to medical school to support her spending habits? 
My daughter was married to a Path Dr, I buried her at 29 years old because she wanted a divorce. 
She knew she could clean him out but instead he was smarter than her and pushed the right button s ent her to the right doctors he said for help. If I did not tell you how my daughter passed on . SHE COMMITED SUICIDE with his gun his father blew his brains out with. 
You doctors think you are so smart. Here you make all that money but its ashame you cannot even afford to enjoy it. I DONT FEEL SORRY FOR YOU AT ALL. GO BROKE DUMMY.. 
Maybe you should have taken ACCOUNTING 101.
