Leave him. Just standing around, wishing, won't fix anything

Incidentally, when/if you do leave-make sure you tell him that he will have to continue helping to support your child. If he doesn't, you'll enforce your rights through a DNA test if it comes to that/court. Because if all the money is disappearing, that's bad. Particularly for little babygirl. You deserve better than this. But if you won't do it for you, do it for your child. So she doesn't grow up in a household that she can wonder "Is this tension because of me?" And so she gets the support, love and positive relationships that she deserves.
