I know I had stocks that I inherited that became marital property. I could have kept it separate when I first got them, but I never dreamed I would ever get a divorce!!!
It does seem odd that she is more worried about splitting up finances instead of trying to repair the marriage. I hope you don't agree to anything (even verbally) just because you are such a gentleman!!!!
Will she go with you to counseling? I know you invited her, but wondering about her response.
