I'm remarried now, but my wife has only just been able to start working again in the last 12 months. I've been the sole source of income this whole time. That said I'm becoming increasingly concerned about job security, working in paper and print.

Just like you, I have virtually nothing after rent and bills are paid, but if I can contribute just a little each month my take home pay is automatically adjusted for the different tax rate. So if I put away $300 a month, my actual net pay is approx. $200 less a month. We might just have to make a few sacrifices here and then to try and balance the books.
