My partner of 20 years has flipped over the fact I gifted my 14 yr old niece £50 cash for Christmas. He works full time and I work part time as we have two DD. He said it was too much money and I am wasting his money. We have joint finances and he now wants us to have separate finances and I have to pay my way (his words). He spouted out lots of abuse about how I am robbing him and he pays for our lifestyle and he is fed up. I am really hurt and don't know how to get past this.
AIBU gifting my niece £50 or is he?
