You don't have to be the one to file for divorce, but really - unless he is giving you a boatload of money right now, you need to file for a temporary order of support etc.
Also -it may financially be to your advantage to file NOW, while you are still unemployed, than a year from now once you have completed your training.
Look after the money which is the BUSINESS part of all this. Don't trust him to be generous, get it in writing. Protect yourself and your kids. You have a complicated situation and you need an attorney who will fight for you and your daughter.
