Hi, keepquiet,
Gambling is an insidious addiction because its effects are not as obvious as drugs and alcohol. My ex is a gambler and I only found out when the bills started coming in and the house was going to be taken away.
You *have* to protect yourself.
The second time my ex almost lost the house, we divorced. I would not let him make me homeless.
I wish you luck. You are young. There are other people to love that will love you back. That may sound harsh, but, it is true. Until he helps himself, there is nothing you can do but protect yourself.
I'm sorry.
Shalom!
