I am 71 years old and married since '87. My wife's money always been hers; mine has always been mine. Over the years, she has been quite successful (she more so than me in absolute terms; me more so that her in percentage terms). My two daughters have followed our lead, have pre-nups and segregate their personal assets (including salaries, wages, etc.) from marital assets (what they decide to contribute to common expenses).

INHO, the "default" assumption of financial sharing that seems to go with marriage is fundamentally flawed as the party who contributes more should be able to walk away with more. Otherwise, staying together becomes intertwined with cash/risk/asset management issues. Ugh.

I'm sorry that you're going through this truly burdensome transition. I urge you to identify and market the values/skills that you have and leverage every free tool that you can find to help you.

Ageism is real but the Internet offers the opportunity to present yourself as if you're 40 -- not with false photos but rather with keen insights and value-laden offers. I know it sounds like bullsh*t (and it often is) but people do make money in this "universe."

I wish you the very best.
