Some excellent advice on here ....especially SEPARATE bank accounts ....Debt counselling and the setting up of a repayment plan. Is the credit card company threatening CCJ for unpaid debts ? (very common now, and you are not always told !). DO NOT use your savings to rescue him.
This may sound harsh, but it is the only way. Would he prefer to have to live on his own in a rented flat ? you could ASK him that ...see what his reaction is. With separate accounts you would be in charge of your own money.
In my case, my first husband was a compulsive gambler ....he had a really good, well paid job as a director of a reinsurance broker at Lloyds of London. He earned a six figure salary. He spent a nine figure salary .....not fun ! In the end, I phoned his senior directors and told them (he was, apparently, about to be dismissed because of dodgy accounting on his part)....the directors summoned me and him and set up, in front of him, a separate bank account in my sole name, and transferred all his salary and bonuses into that ! Happy he was not ! We had a lovely house, a daughter at private school, two cars, etc etc etc ..... and I took over all the debts, loans, et al ....I paid off the debts, bought new furniture for the house, etc ...but it did not stop him threatening me every Friday night (when I went food shopping) that if I did not get him 300 pounds cash just for him, and hand it over, that he would beat me up (he did, sometimes ....but not seriously ...broken ribs, broken finger ! ..but as I was working for a divorce lawyer at the time, I took photos of the injuries, went to the doc to get him to attest to the injuries, kept a file of all the letters, debts, CCJ.s et (in my filing cabinet at work !) ....in the end, he ran off (good !) with a local barmaid ....I sold the house, got half of the insurance policy monies, and moved 200 miles away ! Result ! a couple of years later, I had a phone call from the woman asking me why I didn't tell her he was a gambler !!! by then he had lost his job (stealing or converting money !) ....lost the large old vicarage he bought (I don't know how ....think she used some of her money ) ....ended up in homeless hostel, had a further 6 children .....then had two heart attacks ...have no idea where he is now ...think he is still alive !!
My mother used to say The Mills of God grind exceeding slow but sure !...not a religious person, but my, was she right !
Also ...watch your household goods if you go down the separate bank account road ....my ex used to take my daughter's toys, clothes, all our wedding presents, anything that was sellable, and sell them at car boot sales (without me seeing him go out at 06.00am on a Sunday !)...he even took bottles of drink from the drinks cabinet (I kid you not !) bought a book of raffle tickets, and flogged the tickets in the pub ........I could go on, but I am sure you have read enough !!
Bon chance !
