Just catching up....I think it is the time to get YOUR priorities in order now. Never mind what your W is doing or not doing.
1) Get some monetary support from your parents to cover the most important basics: food, bills, etc. You cannot expect your W to contribute nor count on her to do so. When you get a job, then you can pay your parents back.
2) Get a job that will allow you to support your family. That is the immediate need at the moment. Does not necessarily have to be your career...perhaps in time when you are able. If you do happen to land your "dream" job, then all the better!
