Is it possible for me to win the divorce case?

My wife and I are married 18 years. When we met, I was a commercial photographer; work was not at all secure. When we got engaged, we decided I would go back to school and become a podiatrist, a field that interested me. During this time she was working in a boutique store as a sales person and would model from time to time, making a fair income. Whatever money she made, we spent going out. Shortly after our marriage she stopped working and decided she would go back to school to become an interior designer. It took her 4 years to complete her 2 year program. She took out student loans to pay for her courses. I also took out a large amount of student loans to support us and pay for school. It took me 5 years to complete the prerequisites and podiatry program. During this time we were renting the first floor apartment from her parents and they were giving us a break on the rent, about 1/2 to 1/3 the market rate. After my program I entered a specialty residency at the VA hospital that took 4 additional years to complete but was a paid program making ~60K/yr. After her graduation, she could not find work in her field. She held a job briefly in a furniture showroom but soon lost it and HAS NOT WORKED SINCE. This was approximately 2001. My income at the VA went primarily to paying our student loans and therefore we continued to rent from her parents. The residency consumed a lot of my free time and we could not go out very often at all. This is when our relationship started to drift apart. She was happy to just sit home and be a housewife, buy her fashionable clothes, and spend 2 hours in the gym. She couldn't even spend focused time to get her portfolio together to go on interviews. As a housewife she was horrible, she let laundry pile up, she kept the house full of snacks and junk food, never cooked healthy meals, there was dust all over the place. She would put work on other people like her mother and father, something I really had a problem with.
