I dont get people / couples who stake claim to 'their share' of joint income.
I have a mate who works full time as a teacher. £40k odd. His wife works part time as a teacher and the rest of the time with their child. He makes sure that they keep their money seperate but that there are 'proportionate' outgoings.
Every month he bangs on about having to bail her out and loves the fact that each year it is he who pays for the holiday etc etc and that he has managed to save X hundreds etc whilst she has to ask for £20 to pay for a day out whilst she looks after their daughter! FFS!
Its like he needs to feel in control.
My advice: put it in one pot and just talk to each other or discuss about what you are spending it on. Open and honest relationships work better.
