LMNW, Unfortunately you are far from alone with stress from the finances these days.
OK, you made a mistake with the house, but it sounds as if your W is trying to understand.
Also, consider that being together is probably saving you all kinds of hidden costs. You are no longer supporting one and a half households--you are supporting one.
How is your little girl? Realize it is the child fantasy to have parents back together, esp. preschool age....
