I do not have any good news I'm afraid, unless you choose to break free from this man and his habits/addiction.
I can tell you a short story-
A lady I know is now 75yo. 29 years ago she met a man that was penniless and she owned her own home. 2 weeks after they started dating he pressed her for money and lost it all, gambling. She nearly broke it all off there and then but he was charming.
Throughout the next 28 years he purchased the best of everything always with her money. In fact last year 2020 she went into an aged care facility as she has parkinsons disease, bad heart etc...for 9 weeks. During that time he convinced her to take out a reverse mortgage on her house to get a new kitchen, driveway and entertainment area. So $80,000 was taken out on high interest loans. You guessed it, when she returned home none of the renovations were done, the $80,000 was gone to gambling (horses, pokies) and finally, all her pension from 9 weeks was also lost.
A few weeks later he got cancer. He promised her no more gambling. He was in charge of the bills as she was too unwell. All the promises meant nothing. He then began to lie about paying the bills, instead he got 3 credit cards (in her name) maxxed out and spent their pensions on gambling.
He passed away last January 2021. The bad debt letters kept coming for 5 months. She sold her house to enter aged care permanently and was $120,000 worse off due to his debts which meant- she was not able to secure a nice aged care room, she had to settle for a shared room.
Her comment to me recently was "I was with him 28 years, it shouldnt have lasted 2 weeks.
I'm sorry to give you only one side of the story. He had a good side in that he raised a foster son for many years. Unfortunately that was overshadowed at his funeral by the hurt he caused.
Sometimes we have to cut our losses. If you choose to, there is a life out there that includes control of your own finances. I know you are alone but you will find friends and feel better once alone. If thats what you choose to do.
Either way we are here for you. Brush those suicidal thoughts away, you have much to live for.
