umm... he can't do that hon. You have rights as his spouse, and that includes the marital home.
If he's filed, great. He can take on the expense. And you? You can respond to the divorce with your own demands.
You are in a good position now. You are his wife, and have been for 10 years. Legally you are entitled to a LOT. He is not in control here, I hope you know that.
The fact that he wants a divorce gives you a lot of power. Because you can delay what he wants, or outright ignore it.
