My Husband just Quit His Job

I am 32 weeks and have preterm labor symptoms. I am not sure when I will go into labor or stop working. But he told me he quit his job today because this is not his destiny. He wants to be a DJ, which skill he has just learned for a short while!  He wants to be completely off for a couple years that he can focus on music. I really want to yell at him screw you selfish man. With a baby coming you put all finance stress on me?!  I am so davastated right now... He won't help with the baby even he stays at home. He never took care of me even when I was super sick. He only thinks about himself. Marrying him is the biggest mistake in my life. But what can I do? Divorce under this situation?
