My Husband and I have a main join account and a secondary account linked to our credit card which is in his name and I am a second card holder. I have the banking app for the main account but not the secondary account. We have disagreed tonight as I asked to be able to view that and he doesn't want me to as he believes I will scrutinise his spending. I have mental health issues and I struggle with unnecessary spending so he does have a point however to remain equal I believe I have a right to see it and him denying me is wrong. Is there a form of manipulation involved here or what should I do? This all came about as he bought an air humidifier which is huge, unsightly, draughty and noisy and I learned tonight cost £200 which I was rather annoyed about and I said I should be involved in a discussion about spending that sort of money and he said he can buy what he wants without my approval.
