Considering divorce but just looking for some insight on how much of my net worth I might lose from people who have gone through this before. 37M (me), 34F married 8 yrs two kids under 3.

Both of us have worked full time jobs the entire marriage. For the majority of the marriage our salaries were very close but I always made slightly more. I started a new job a few weeks ago that bumped me up, though. Currently her salary = 95k and my salary = 122k.

We have both always maintained separate bank accounts. Hers = 125k mine = 10k (I invest most of my money)

We have both always maintained separate investment accounts. Hers = 1.8k mine = 1M. I had my account before we got married, but unfortunately the majority of its value came during the marriage however anything deposited into it was my own money. Nothing was ever co-mingled.

My 401k is about 42k and hers is about 30k.

We have always split expenses proportionate to our incomes. I am mostly curious given the above info, what might happen in terms of maintenance, child support, or because of the large value in my investment account if some judge is going to hand her half of it or something. Am I totally screwed here?

EDIT: We live in IL
