Hi EHO
Your husband chose to gamble, it was not your fault.
Sadly, compulsive gamblers, who chose to gamble, will lose and then seek to blame somebody else. It is easier for your husband to blame you than it is for him to accept responsibility for his poor behaviour.
The highs and lows for gamblers are often extreme. Selling his car 2 weeks ago probably made him feel good, he had some money but typically he used that money to indulge his addiction. Within days, his euphoria at having money was reduced to misery because it had all gone.
I cannot tell you what to do but I believe, for your own sake, that it would be better not to keep calling him, allowing him to hurt you further when he declines your calls. He is reacting angrily to his loss and he is using you as a target for his anger.
It is hard, when there has been a glimmer or light, to find yourself confused and in the dark again but I suspect the glimmer only came about because he sold his car and not because he has sought help to control his addiction.
Please keep posting EHO. I understand why your post is all about your husband but you and your health are very, very important. Give yourself time to breath and enjoy life. Please tell me more about what you are doing to make a happier life for you and your children.
As ever
