What's going to happen if ppl marry based on love & attraction they'll have a happy life until money's the reason it becomes hard. If ppl want to get married they've got to discuss their finances before it's official.
To be honest, people who fall in love for real won't have problems in the marriage even if there is a shortage of money and resources for sometime, because they value each other and they support each other in bad times, and that's how you can enjoy good times together when the hardships are over. Life doesn't stay the same forever, and those who understand this will always have sorted relationships, because if your wife understands that if today is a bad time, tomorrow can be a great time financially, so they wouldn't give you a hard time for it as long as you are trying and doing the best you can.
In a relationship where the wife keeps a negative attitude towards the husband only because he is having financial problems for the time being, that relationship is toxic, and it won't last very long, and even if the financial problem goes away after some time, the things and moments that the husband has gone through wouldn't be forgotton, and they will never be proud and happy to give the wife a better life because she couldn't show any morale support when he needed it the most.
