i think it’s the thought pattern behind it thats the question.
my first question is was it his house that you moved into? in which case it implies he feels it’s STILL his house. not “our house”. that’s not good. i take it youre married so it’s half yours now in the event of divorce.
second question is where did the money come from? the most sensible way to run a household is that both parties contribute equally or a percentage of their income into some joint account or kitty arrangement. so if he’s taken community money and made expensive changes with it thats bang out of order. it wasn’t his to take it was “ours”. hes stolen it from there so to speak.
third if you’re not contributing as much due to having mat leave or are part time looking after kids etc does he feel like he’s the big man wirh the important job kind of doing a favour for you the poor little woman thats his possession so he feels good about Doing A Nice Thing for you. that’s bad too.
or did he spend his own personal savings doimg this because youd mentioned “i’d love a kitchen island” or whatever and he genuinely thought he was doimg a nice thing out of love and doesnt understand how you feel now.
how would he like it if you took community money and unilaterally bought a car say, without researching etc. just “because it looked nice and you said you wanted one” would he be ok with that!? i bet not. i bet there would be lots of questions about engine size, insurance cost, petrol/electric etc. Sizeable purchases need research consideration and agreement prior.
that’s the analogy uf use in my convo with him. we are a partnership. we should be equal. this is too large a thing for one of us to just do.
