You want a divorce, but your spouse does not. Your spouse seems to believe that as long as he or she does not agree to a dissolution of marriage, then you cannot obtain one. Can a dissenting spouse stand in the way of dissolving a marriage?
As long as one spouse is willing to allege, under oath, that there has been a breakdown of the marriage relationship to the extent that the legitimate objects of matrimony have been destroyed and there remains no reasonable likelihood that the marriage can be preserved.
You can divorce your spouse without his or her consent.
