... however he decided he did not want us there and forbid me to go back inside the house. Can he do that?

He can do whatever he wants. It is his house, it might not be fair that he offered the house to you so that you two would have a roof over your heads and then tells you that you can't go back. That isn't a nice thing to do, but legally he can tell you he doesnt want you there.
