First steps of divorce with baggage?

By baggage I mean a line of credit..hefty debt there. A mortgage, a car, personal and shared belongings in a fully elaborate house. Both signatures are on the house, line of credit, credit cards, joint accounts, and we share a business/accountant/tax payments. My husband let me know last night that he wants me out of the house by the time he gets back from his business trip...three days from now. Can he realistically expect me to be out? What should I start to do now? Pack? Call a lawyer? Should I demand to be paid 1/2 for the house first? How long should I wait before contacting the bank and what to tell them? I am puzzled but have seen it coming for a year or more.
