Rodolphus is fine. He was a little shell-shocked to begin, but he's back to himself now.
And it isn't the same thing. Rodolphus would never be selfish enough to put me in danger like Lucius has done to you and Draco. In fact, I don't think Rodolphus would do something that would put you and Draco in danger either.
If you need a place to stay, you're welcome at the Lestrange manor.
