You taught her that she needed to eat to go back to sleep, so now she needs you to help her unlearn that. And that does not mean leaving her to cry, but actually helping her find ways to calm at night without food.

It will make for a few long nights, try to split them up with your husband (since no nursing there is no reason it has to be you).
