A bit of backstory; DH has a history of drinking, using credit cards to buy alcohol, and hiding alcohol from me. He’s cut down recently, though have noticed £150 a month is going from our current account. I’ve never seen him use cash before, all his other purchases are covered by card. I calmly asked if he knew what the cash withdrawals were for and he said ‘bits and bobs’, £90 has been used in the last two weeks whilst he’s been at home, and every expense in this time is covered by our direct debit card. He’s also going to bed after 4am 4/5 times a week, he says he’s watching films and think he is. I think I just need to write this down to tell myself that something is going on. I know if I pursue this issue with him further he’s going to say it’s his money and he can do what he wants (though it’s a joint account and we earn similar amounts). Though I can’t just leave it, it’s so much money. I don’t know what to stand up to him. AIBU to ask him what’s going on?
