Just so you're not screwed or homeless, I suggest you start looking for employment because he is not obligated to pay you spousal support; you were never married. He is only obligated to pay child support and depending on where you live, in the state of NY the percentage is 17% of their pay. Another thing, don't think the judge will not award him custody because he works to much, that's not a reason. He has a source of income, you don't. He'll have shelter, you won't, and he'll have the means to take care of his child. So, please don't take that thought you have of him not getting his child for granted, you will be highly disappointed if the judge rules in his favor.
Start getting your act together, look for employment to show the judge that you are looking for means to support yourself and your child. Your soon to be ex boyfriend is not obligated to take care of you!
