There is nothing about what is in our heart to consider. You have to consider the law and what you are each entitled to. You have no chance of getting everything any more than he has a chance of keeping everything himself.
You need a lawyer that is experienced, will consider you assets, debts, income, needs etc and give you a legal opinion as to what you are entitled to.
Then the lawyer will write to your spouse asking your spouse to get a lawyer and explaining that if that doesn't happen you will proceed to Court.
The Court will make an order that divides the assets fairly and if you are in need of support that court will order that as well.
Because you are depressed it is hard for you to get up the energy to deal with this but you are getting trapped into a situation that will become worse if you do nothing.
So find a lawyer that you believe is competent but compassionate and you will start to feel better and at the same time there will then be a light at the end of the tunnel.
Family law is a terrible system for all but by retaining a lawyer you trust you are making the best of a terrible situation.
