Boy! You sound so much like me! I have felt exactly how you are feeling as far as the attorneys go. I too have gone thru 3 different attorneys. The last one would get me all fired up about what we need to do and then he wouldn't do it. I would ask him to do certain things... and he agreed and then wouldn't do it, making my situation worse. He'd make excuses and back pedal. So, as much hassel as it is, I found another one. I am hoping this one goes well. As for temporary support, I do believe there is a way to get that. Go to your local court house and ask around. I know when you get a restraining order, you can also ask for temporary support. I believe when you file for a divorce, before it is final you can also file for and be awarded temporary support. You need to be supported. In times like this, and maybe I'm a bad mom to think this, but I would feel like dumping the kids on him and say, hey, you take care of them so I can go to work! I mean really, why does the woman get stuck with the kids and no support while the man hoards his money and doesn't take any responsibility for tending to the children. It's crazy. They are his children too. He needs either to support you or take them off your hands once in awhile so you can work. Especially if he's not working! Men just tick me off. I have no interest in ever being in a marriage with a man again! They seem to all be the same as I listen to story after story of the same sort of plight women get stuck in with men.
Best of luck.
