Your husband sounds like an arse, Thats the way I am reading it.
With an income of much less than your husbands, we a family of 6 and I dint work for many years, we coped, a little, But i am selfish ..
I got into massive debt myself, but I spent it on frivolities, Days out for us as a family, stupid computer games etc etc, food that I wanted and so on I had 5 credit cards at one point.
I have to add for the last 2 years I have had a job,
It took 10 years, but last month I confessed to my DH just how much in the shit I was, (he had no idea)he went mental and was supremely angry with me very justifiably so too.
It was 10K and that still makes me ashamed and very very sad, I feel like I have just wasted what could have done so much good for us.
I have to add for the last 2 years I have had a job,
This pay packet is the first of what will be a year long battle of me paying off my debts and for want of a better term, screwing the family over as I no longer contribute to the daily/monthly upkeep.
But my husband is not an arse, he loves me and has forgiven me, totally, (with the caveat he will divorce me if it happens again)
If he loves you, he will forgive you (after awhile, he will be angry at first) and find a way to help you, if he does/t you will be better off without him.
