I tried the collaborative approach. My W wanted everything. I was going to be left with .01% of my income. I gracefully offered half which is a lot, and she declined. I was forced into the full blown legal system.
If you can do it collaborative approach, do it. It's better for you and your kids. The lawyers make their $ by dragging it out and nit-picky charges. Just stick up for yourself and don't let her take advantage of you. This is her choice not yours. She has to live with the consequences but you do also.
If you go down the D road, don't expect reconciliation. Just make it as difficult as possible for her. God doesn't like divorce. Man up!
