For many people their parenting plan equates to less time with their kid(s), but in reality that time with your kid(s) increases in its quality. When two parents are living in the same household together, the parents tend to interact with each other more frequently than they interact with the kids. When there is only one parent with the kids, there tends to be much more parent to child interaction occurring. As such, many relationships between parents and children are strengthened post divorce. Although you may see your children less frequently, you may have more quality time when you are together.
As far as the finances go, two households will probably be more expensive than one. On the brighter side, you get all the freedom to decide how to spend your money. No more need to explain or justify your spending habits to your spouse.
