Going to go consulate with a lawyer tomorrow. Have 2 kids, married for 9 years, what should I expect during the divorce?

We can’t agree on literally anything so I know we won’t agree on anything regarding the kids or settlement. I want to buy her out of the equity in the house we purchased back in 2022, and honestly just want 50/50 custody. We live in a state all away from both our families and have been separated for a couple months but live under the same roof (unfortunately). We both don’t make much money but she could never afford rent where we live let alone with our kids.

I just don’t know what to expect during the whole process, how long it will take, so on and so on. Anyone want to share their experiences?
VA btw
