I am pretty sure IANBU - but please tell me if I am.
DH has always earnt more than me.
After we married we got a joint bank account which all our money goes into (inc DS maintenance and child benefit) and all our bills go out of (inc maintenance for DH 2 kids).
This was mainly because DH had racked up quite a lot of credit card debt and was demoted at work, and he wanted me to take charge of our finances. Our finances were a bit ridiculous too with constantly transferring money to each other for shopping.
He works away in the week where he lives for free but obviously eats, DS and I use the gas and electric, and basically have to live here (eat etc) and we have a mortgage.
DH and I each have our own personal account which we put the same amount of “spending” money from the joint account each Month.
Finances are now a bit straighter and a lot of the debt paid off. We have taken out a loan to do some things to the house and I have a loan for a newer car (I have to have one for work- my old one needed £2000 of work doing to it) which I have agreed to take in students to pay for (he has given me endless amounts of shit about buying the car which he agreed to at the time).
DH has unbeknown to me now got himself into another load of debt (not huge) over something really stupid and taken out a credit card to manage this. Most of his “spending” money is now going on this and he is basically using the joint account as his own personal account.
He has also been “re” promoted at work and is saying that he should be able to dived what he likes because he earns more - although the arrangement was good enough for him when he was earning less.
AIBU to think he is in fact very misguided, selfish and potentially his spending is out of control?
