My wife has a Lumia windows phone the previous model to mine and she has received the windows update to download Cortana.

We don't have that information here. Updates are as much a mystery as it is to you.

You haven't mentioned which country you are from or if you're carrier locked.

You can check here to see how the updates are going - Software update for Lumia with Windows Phone 8 - Microsoft - Global

Things are very slow lately.

The denim update is done by Microsoft or your carrier and only they know when they realize an update. For evere phone model there is a separate release so that's why your wife has the update already and you not.
See attached Microsoft website to check if the update for your phone is already released. Be aware that this web site does not indicate when an update will be realized it only shows which are released.
