Where you have no grounds for divorce, you may be able to end the marriage through an action for Separate Maintenance and Support, sometimes called an action for legal separation. These actions address the full range of divorce issues - child custody, visitation, property and debt division, child support, family support, alimony and lawyer's fees. In this action, you can have the court rule on all the issues listed above and decide those issues with finality. Once those issues have been decided by the court, whether by agreement of the parties or as the result of a contested trial, those issues are res judicata, a legal term meaning that the issues cannot be re-litigated.
The only remaining issue would be the divorce itself, which either party could obtain after the parties have been separated for one year. For the separation to be valid, you and your spouse must live in separate residences for a full year - sleeping in separate rooms does not amount to legal separation. An order of Separate Maintenance and Support also offers many advantages for people who want to be divorced. It allows them to settle issues without having to wait a year before you can even begin the action. Also, after the order is issued, adultery is no longer a ground for divorce.
