Hi sunset and welcome to the forum
The reason Northern Rock have asked for the adjournment could be for a number of reasons - but the main thing is that they have not rejected it. Your proposal should have clearly explained the reasons why your wife is not working, and this could have avoided the need for such delays.
A good IP will try and answer all of the creditors questions within the body of the proposal, to try and avoid delays and to ease the decision making process for the creditors.
Good luck with the adjourned meeting.
