For some context DP and I have one child together (aged 2) and one on the way. DP has a child from a previous relationship (aged 15).
DP and I are both relatively low earners, me particularly as I only work part time due to childcare. We do not have a joint bank account. As he is the higher earner he pays more bills than me, though I still pay a few "big" monthly bills, then I pay mostly for day to day ie the weekly shop, petrol for the car, clothes whenever our DC needs them etc. Typically due to being low earners, as much as we live relatively comfortably (never having to count pennies), we do live wage to wage with little left over.
Now the reason I'm posting is, I have recently found out DP has saved by almost £1000 for him and his DS. His DS has a new and always expensive hobby every few months. So he is planning on spending this money on days out for the two of them, and buying gifts for his son, in relation to whatever the hobby is this month.
This has naffed me off a bit. Now if it was totally spare money then no issues, I'd know its not my place to tell him what to spend on his son but, firstly he never spends a penny on our DC together, leaves that all to me. And secondly there is household things that we really need but have been putting off buying because the money (as far as I knew) has just never been there at the end of the month when everything is paid.
Would you be annoyed if you were in this situation?
