You present an interesting dilemma.
You want him to give up his money for love. Because in your mind, you are worth whatever income he'll forego due to divorce.
I really think the answer to this comes down to being a man versus being a woman. Like, I understand your argument. I truly do. I just think that its asking a lot for a man to part with his life's work just to show you that he loves you. Now, from a business standpoint, he knows the rules, you get a divorce, if you live in a community property state, things get split down the middle. At some point, a divorce will happen. However, his wife isn't interested in a divorce? That is odd to me.
So for you two years, his wife has been okay with just being separated and NOT getting half of his business and earnings? Something's afoul here. Does he just plan on staying married to her forever?
For me, I feel like he just has no idea what he's doing. I'm sure he loves you. But you're making his love for you and his business all apart of the same basket of monkeys. And they're not. He needs to take care of his business AND deal with you and the two are mutually exclusive.
To me at least. Of course you can say, well, until he divorces her, we can't get married. To which I wonder aloud, this dude obviously has a principle issue over his money enough to stay married just to keep his wife from half of his business. You think he's in any rush to get married?
I think you're looking at that grand gesture of risking losing your money for love in a movie sense and I'm not sure if that's fair. But it does present an interesting question.
To me...he should do it because it's going to happen sooner or later, not because of his love for you. That's secondary in my opinion. Your love affair on the other hand, is likely what you think matters most and I'm just not sure that's the main issue here.
I'd love to hear other opinions though.
