Of course but if the poster has been in low paid work all her life like my sisters have and they are of a comparable age the advice may be different.

I got like that, just bloody sick of it. Slightly different circumstances, as my partners business went bust leaving us with a lot of debt and him unemployed. Our life savings got swallowed up by the debt.

Op I was like this too. We broke everything down on spreadsheet down to last penny. When dh saw it like this it really spurred him on to search for cheaper energy provider, switch to pay as go mobile contracts, etc. We then had every penny for petrol covered, shopping, etc. Once we did it we found it was easier knowing exact what we had to spend and that taking money from specific weekend money, meant we could still have petrol money as that was separate. So now I don't worry about it
