So, I’ve already spunked my Fun Money budget for this month, which is fine. We took the kids out for a nice dinner last week and had a takeaway the week before, and I’ve had a few bottles of wine in the last month, plus bought paint which I’ve put in that budget as it was me who wanted to decorate, DH would have waited.
The kids asked the other day if we could have takeaway this weekend and we said no as there’s no point having a budget if we don’t stick to it.
So yesterday afternoon my sister called and said her date had cancelled so could she come over with kebabs and gin. DH was out working so I said of course that was fine, and she paid (she always does because she only ever comes over if she’s got no other options, she has a thriving Tinder and social life 
so she knows she takes the piss a bit by using me as a fall back).
A great night was had. But DH is a bit pissy with me. Not horribly, but he says that in his mind if I’ve already rinsed the budget and we have to say no to the kids, I’m out of order for accepting a free ride from my sister.
Similar happened last month but it was going out for dinner for her birthday, I’d initially said no as again I’d already spent my budget and she said not to worry it was on her.
DH says I’m having my cake and eating it.
I’m a bit hungover so probably taking it too personally but is he right? Should I be declining invitations on principle?
