Also - if you learnt on a four seater you can still take your wife if she sits in the back and you have an instructor sitting with you, if you did not learn in a four seater you can still take your wife and instructor and use the opportunity to check out in something new and bigger.
Not saying you should not be P****ed of at the CAA, just suggesting ways of getting on with some flying whilst waiting for them to get their act together!
Good luck
