A very tough situation to be in, Stone. Of course the least you seem entitled to from a moral point of view, is the money you invested in Greg's business.

I don't know the exact details of his business, but it might be hard to extract the money now, if you don't want to ruin the whole enterprise. So it may be kind of impossible to get all your money back now.
But on the other hand, the investment you made, probably comes with a few rights of your own - you could use these.

Knowing that you are in the financial field, there must be ways to work that out. There must be solutions available without screwing things up with / for Greg.

You invested an amount of money in his enterprise, and you could get him to invest a similar amount of money in your house. Again, I am not an expert in the financial field, it should not be impossible to arrange for that, without the whole marriage / divorce ordeal.
