The solution is simple- make it clear in initial points of contact that your financial advisor has "locked up" most of your Net Worth and has you on a budget.
Having worked 30 plus years in the securities industry I have seen some interesting corporate/personal structures that prevent someone from being able to make claim against your assets. You should put such structures in place now rather later and stick to keeping your assets separate.
I have found that I am somehow much less attractive when the fact that my Net Worth is impaired.
I'm not intimidated by a weathy woman or a beautiful woman. I think if you feel confident in youself it doesn't matter about the other person's weathy, beauty, etc. I find we all have our problems, insecurities, and foibles no matter what we have to offer. None of us are perfect. I figure wealthy or beautiful women are no different than other people once we look inside.
here's a line I have used....and it never EVER fails.
When it comes time for the bill or check; and YOU know it's easier for you to pay, and it is no big deal...pick it up and say, succintly, innocently but to the point-
"I'll get this and if you don't let me, well then when it comes time for the sex, then I'll have to insist on abstinence."
I have had a sheepish grin and the check handed to me immediately. I have had their hand pulled away ASAP. I have had a huge LMAO; but I still paid. I have had an embarrased pause with nothing to say. I have had a "it's all yours." "whatever you say." "whatever makes you happy." "not a problem."
And all of the like---but not once have I ever had a man insist on paying after that. And using the right tone and inflection of voice it seems to come off without any intimidation factors. it just seems to take the male ego on money right off the table.
