Hello Intromom
I'm sorry to hear that you're going through this

My advice is to get some legal help from a divorce attorney. If you're a stay at home wife... you maybe qualified to collect both alimony and child support from your husband. This is a temporary fix to help stabilized your finance... In the mean time start sending out resumes so you can start working again.
Just a FYI... If your husband is truly a narcissist... He may start psychologically abusing your daughter by coaching her to start hating you. This is called parental alienation syndrome. He might very well use this strategy against you after the divorce has been finalized. Just be alert of change of behaviors in your daughter.
