Know Someone With A Gambling Addiction?

I do and it's destroying my family.

I've tried to see where he's coming from.
I know little about what it's like to have an addiction.
But, he's not trying to get help. He won't.
He's pushing everyone away.
He's gotten so many chances, so many.

I can't seem to forgive him now.
Not right now anyway.
€500 in a day.
It's not his worst but he's told us so many lies.

I can't take it. Him snooping around my room when I'm out.
Stealing money I had saved for my newphew and a trip.
And he lies straight to our faces about it when we know it's him.

What can be done?
