I just need to vent lady's

I am just so beside myself right now, I have been with my husband for four years married almost a year. I am 15 weeks pregnant tomorrow. My husband can't keep a job, and I feel like I have to do everything. I feel like he is a child, every time I try to talk to him he gets offended and gets all mad. I have thought about just ending it all, but I don't want to just give up on us. I love him and he can be a sweet man, living and caring. All I want him to do is grow up and provide for his family. Our baby is due in September and I work part time right now trying to pay the bills and get our baby what he/she will need. I feel alone in this. Our family's won't be much help in getting things for this baby so I am on my own. How can I get him to understand that he needs to step up and be a man, father, and a husband. I just feel lost right now and alone. He is 24 years old and I am 34 years old. plz no bashing I know he is young and this is his fist baby, it is not my first child I have five children from my first marriage, so you see i just don't want to up and leave I love him bit I don't know how to make him understand what needs to be done. I have heard that men don't become a father until the baby is born but I need him to step up now. Has anyone else experienced this and how did you fix it. Thanks in advance. His last job he quit because he didn't like it he was not getting paid much but it was steady income every week he got cash for that job, now he has the opportunity to take my job when I go on leave but old if he will keep it.
