Which way of these should I want to proceed in regards to cost, time, and best financial result for myself?

We are very amicable, friendly, and great/involved parents with our kids. Our only issue has been her wanting divorce (she just fell out of love with me) and me trying to save marriage thru counseling and saying I still love her and don’t want divorce for past year. If I relent and get on board we can power thru process in friendly manner. I’m considering that now.

But want best financial result for myself. I will have to pay alimony and child support. I make 1.7x her salary. 2 kids, 11 and 9. 12 year marriage.

If all of the above are options to proceed with which one should I choose?
