DH and I both work, he works FT and I work PT 0.64 WTE.
We have our own bank accounts and a separate joint account from which we pay all our bills and rent outgoings, which adds up to around £1200 a month.
Currently DH pays in £650 a month and I pay in £550 a month, plus I probably do 3 of the 4 weekly shops a month. I think this is unfair, as I have very little, if any, money left at the end of the month, when I know DH has money left, although he also has other outgoings such as credit card and loan which he ran up when we weren't together.
How do I work out a fair way to contribute to our joint outgoings?
We are in similar jobs, so if I were FT I would earn a similar amount to DH.
