I am 2 years into a divorce which is finally set to go to a 3 day trial next week. I have exhausted all of my available funds (over $100K) on legal fees. Finally just a week before we go to trial my wife wants to try to negociate things. I am looking for a "nonemotional" 2nd opinion as to wether or not the offer that's on the table is in my best interest or would I be better off going to trial? Please understand that the negociations have gone back and forth many times already to get to this point.
My Wife and I are both Chiropractors. We met in school. She has always refused to work or contribute to the finances of the marriage which is what has lead to the divorce. in a nut shell here is a summary of our assets and liabilites:

Chiropractic practice (annual gross $1.1 million)
associated liability $200K (the oppisition puts 0 value on my personal goodwill which earns 70% of the income of the practice).

Strip mall (value $1.1 mill) liability also $1.1 mill.

Home: value $350K liability $550K (upside down $200K).

Credit card and unsecured loan debt: $220K

So depending on whos #'s are used the net worth is around -$500K. (depending on how the clinic is valued).

The offer on the table right now after much debate is as follows: I keep all the assets and liablites... She walks away free and clear and gets $5K per month for 9 years as allimony. We do have 2 minor children (9 and 10 and have already a 50/50 custody agreement). I make on average $200K/yr. I am told with this allimony payment childsupport brakes even. The allimony is modifiable dwon to a $2500 limit but does not cap off at a max limit.
She was offered the practice and property but straight out does not want to work... just wants to sit back and collect... I understand that with this arrangement I take a lot of risk, but also a lot of potential. What do you think?
