What would the court decide in the following scenario?

If let’s say:
You lived with some multi-billionaire for many years hoping he will marry you,
-and on the outset he absolutley made it clear that there will be no marriage, (it was proven in court),
-and you married him just for his money, (if it was proven in court)
would you get alimony or would the court tell you to “get out of town you shameless gold digger.”
And by “the court” I mean in any jurisdiction you know about.
