Not sure if I am the best to give advise but I have been in your shoes to some degree.
So with in house you are in control. only you or a judge can decide when you move out. This gives you time so use it wisely to work on you. to work on your next move. go through your options fo where you can live. Give W the space she asks for.
Figure out what you want. Not what will cause your W to get angery the least. And whats best for your D9.
i think you are doing well. Dont engage. Know your rights as far as her taking D9 out of the family home. If you dont need things to change right now then dont change them. Move forward when you think its time. You got this.
