How would you feel if your wife did this?

Me and my wife have been married for 5 years. The first three years of marriage, she stayed home with our kids. She always hated it and always complained. Always accused me of making her a slave. I always told her she should do whatever she wants, so long as it was something productive, and it made her happy. She tried several part time jobs, she got in arguments with people at most of them until she settled in at a Wal-mart where she made minimum wage. She would go out and drink after work with her friends for an hour or two an buy stuff. In the end, she was making less than $100 a week, nothing was getting done at home, and I was working a full time job and doing most of the house chores. Finally, she realizd it wasn't worth it. She then went to school for cosmotology, spent $5,000 and got licensed. She worked at several places and kept getting in fights with the owners and managers and she finally decided "it wasn't for her" and "she couldn't make money at it". Then she decided she was going to become a paralegal. She flunked her first semester of college, took BS courses here second semester. Went back the next year, ped the first semester, and now is fluncking the second. Out of two years of college, she has racked up $20,000 in student loans, and I have forked out $8,000 in daycare so she could go. Now with her flunking out we'll be back exactly to square one. Finding something to do with her that is productive. I leave the happy out of it because she has never really been happy. With all the misery, stress, money wasted, and frustration, of her endeavours, I find myself completely "out" of the marriage, like I want a divorce. I started seeing a counselor because I was miserable all the time. He said it is very understandable to have these feelings. My wife thinks I am an *** for even being upset with her, she blames everything on others....doctors, evil college systems, angry bosses, in laws, her parents, our rotten kids, even me sometimes. I can't take her anger, depression, and tirads anymore. She constantly wants people to say there sorry for her, but how much can someone feel sorry for someone else? Doesn't it come a time when you feel like the other person isn't contributing and is just sucking everything out of you? I have tried everything to make this person happy, and she is still miserable and angry. How would you feel?
