Here is my solution. Your girlfriend sounds smart, so I am assuming she land a good job? Take the next four months, wait tables or work as a bartender. Save your money. Buy your girlfriend and engagement ring. Then, take the rest of your life off from work while collecting half a big law salary every year. That was my approach to law school (I failed).
Or, i think you may want to consider going to an LLM program in NY as someone suggested. NYU has a great one, and, although they are selective, it is not nearly as difficult to get in as it is for the JD admissions. This would put you graduating the same time as her and give you more of an opportunity to get a job lined up for after.
