If you want to save your money all you have to do is to invest and make your own bank account so that you have a money that can use in the future.
I agree to you. If you really want to save money for a long period of time I suggest that open a bank account and store there the money you want to save. Then do not spend it on the thongs that do not really matter at all. Be wise in spending it all the time. And if ever you want to your save money to grow then maybe youcan try joining some investments.
Opening a bank account is a good way, but banks always have problems, we send too much money, it is also a scary thing, and so I usually split into two parts, one to send the bank and one to my wife. And I can guarantee women are a very good place to send money, even though I'm not profitable but safe and not allow withdrawal is extremely good, I can assert that I am forced to manage reasonable spending because my wife never gives me money back, if I do not use a reasonable salary, I may be hungry
Save your money in your wife has a risk too. What if your wife cheats on you (or divorce)? To save money in long term, i think gold is the best choice as it has less volatility and will be useful to keep your money value in case your country's currency keeps falling.
