I had to get another attorney in haste before a hearing. This is a new thing for you, and it may take time to learn the ropes, and you may need another lawyer, only you would know that.
You need to get competent legal advice- in my region, it is not unusual for the wife and minir children to retain the marital residence, even until the age the children reach their majority. It is also standard for support to be required when the financial disclosures indicate that this would be according to set guidlines. Only you can know what is right in your case in all of its particulars- competent legal advice is crucial, as well as your getting what information you can as well.
Hope you do all that you can to destress, this situation can be a monster!
Best,
