You buy and sell stock for a profit - plain and simple.
You are married to a person for some benefits - emotion, kid, sex life, living partner, etc.
Will you buy a stock for a loss? of course not. If you know you are going to lose the money, you won\'t do it.
Are you willing to marry to a person, who will not give what you expect? I don\'t believe it.
Since your friend doesn\'t know much about that 2 person, why not start from more tangible thing like incoming.
Let\'s put it to this way - we can\'t talk about LOVE here, because they don\'t know each other. Even once loved couple could get divoce. Why not get the money when you can?
