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.
Yes in some places there may be the customs for the couple to visit a casino and play gambling there together. In my country it is even not consider a good activity to visit a market by the girls, they cannot think about to visit a casino, Only men use to visit a casino and play gambling there. May be few girls are there who like to play gambling online.
If you really want to gamble with your spouse, so you need to search for one in casinos because normally people do not like going for gambling and it is always been treated as something evil and destructive. Gambling affects relationships in the worst possible way once you fall addict to it.
Yes cultural differences can prohibit a couple from visiting a casino together but must we go together at all in the first place? I don't think it has any significant impact on the games we play if we go to a casino with a family but many have sought to superstitiously explain that and i disagree.
May be in some places it is possible to visit a casino with your family or your family may know about your gambling activity, but in my area i do not think that one can even think about that, we always play gambling without knowing any of our family member, because they will never allow us to continue our gambling activity, even we do not like our neighbors to know about our gambling, therefore i think in current time online gambling is the best option for them to play, where they can continue playing gambling anonymously.
Well if you and your partner are both into gambling, then i don't think there's going to be any problem with going to casinos together. Who cares what your neighbors think and say. Though once you decide to start a family, both should mature and responsible enough to know that their hobby should take a backseat.
