I don't think you will get a gambling partner as a wife ,because they won't like to gamble the entire earning money in gambling. Because they won't have money to spend for their make up.Lol
It will happen to the big shot only.If they are millionaire or billionaire, they will get this chance.

There are many couples in Thailand goes to gambling night on Saturday night. I do not think it is big problem between the couples who invest on gambling all the time.
There are billinares in the world who made their life with the gambling alone.
If you able to keep on invest on gambling, it is the right platform buddy.
