And is having £600 to save every month quite a lot? I think it is but I'm getting the impression DP doesn't think it's a lot. There will be around £350 odd left that's to be spent on anything he wish (not bills or direct debits, money that's free of all the normal monthly costs so can be spent on days out, or clothes for DC etc) and for me that's a LOT. We're in London if that makes a diff but not in the inner city
