And it's driving poor dh crazy.
I'm a sahm so I don't have any income. Dh gives me an allowance which is completely spent every month on my own personal bills which is mainly store cards. I've even cancelled my pension because I can't afford it at the moment. He doesn't know that. He earns well and pays money into the joint account which covers all household expenses etc.
I've also been spending a bit of the joint account on things like sales stuff this month, not a lot but enough for him to notice. He's also just found my store card statement which has hundreds of pounds on it, although I can cover the monthly repayments. I accidently paid late over Christmas and he saw the late payment fine and I think that set him off. He had a bit of a go at me tonight and told me I'm irresponsible and taking him for granted. He doesn't approve of finance and told me I should save for what I want, not keep putting it on finance which I then expect him to pay for.
He'd go absolutely spare if he knew I'm also paying off a loan which I took out to cover two credit cards.
He's right, I am shit with money. I hate not having any income, I hate being reliant on him, I hate that all our financial responsibility falls on him and I hate having to ask. He's right not to trust me with money. He earns it, I spend it.
I'm lucky that he's got a good job, is supportive and careful. I feel as though I'm throwing it back in his face when I keep spending it. I'm only buying sales stuff etc, not living a designer lifestyle, but I can't seem to stop myself. I even asked a while back if iwbu in asking him to buy me a new car. I think I probably was! 
How do you get out of a hole like this? I can't really go to work full time till the youngest dc is in school and then I'd hardly earn enough to cover extra childcare etc. I'm not qualified or experienced in anything. I feel shit at the state I've got myself into. I'm trying to live the high life whilst having absolutely nothing to back it up with. He'll get fed up soon and I wouldn't blame him.
