There are 3 top concerns people have in divorce situations.

And of course a second very important concern is the kids. The goal is to foster continued healthy relationships for them with both parents. You need to work out a parenting schedule which serves their best interests not necessarily your own concerns. For example, you may want to see your kids every other day but that could be extremely distruptive for them. Always try to think about what is best for the children.
Third, you will be concerned about where you will live post-divorce. You may not be able to continue to live in the home you have resided in with the soon to be ex and the children. If not, then you may well want to look at where you can move to keep the children in the same school district. You will also want to look at where the soon to be ex will be living. Often the further you live apart, the greater the strain that can place on transporting the children and on their parenting schedule with the other parent.
I hope this helps. Make sure that you have an attorney who will help you address these concerns before and during the divorce process.
