Some context: I'm very pregnant and about to go on maternity leave. Historically me and DH have always paid 50/50 into our joint account for mortgage/bills despite me earning less than him (I wanted to do this), but I've had to have a conversation with him about changing this so that we're both able to get through my mat leave financially. He seemed a bit worried about the impact it's going to have on his money, but understood and agreed.
This week he got a parcel and was a bit shifty about what it was. He went out today so I've snooped in the office to look (know I shouldn't have done this)! He's bought some expensive computing equipment that he didn't need - probably cost about £500/£600.
I can see why he hid it from me, I'm normally very chill about him spending his money as he wants as he's good at saving too and often volunteers to pay for joint expenses outside of usual bills, but at the moment I'm very very hormonal and sensitive on top of being worried about money. We also have lots we want to spend money on and he's said we can't afford right now, e.g. we have loads of work we need to do on our house and we haven't been on holiday in two years. I think maybe he saw this as the last opportunity to spend some of his money on himself before he needs to cut back but I'm feeling really hurt and frustrated.
I guess I'm angry that he hid it from me, but also angry that he could justify this purchase in his head when we have so much going on. AIBU?
