These are one of the reasons why marriages crashes. When someone gets married to someone because of money. Now, if paradventure, the money finishes or something else happened to the money along the line, what do you think will happen?
So, marry someone because both of you love each other and then, build and develop yourselves in love, peace ,unity and in all, in the fear of God and every other thing will be added unto thee.
No it should be based on genuine feelings, not financial gain.
