After the elapse of a period of time, nobody much cares if the reason you only had every other weekend was because the other parent truly wouldn’t “let” you have more time. Although that may very well be the case, and although you may have let your spouse control the situation in order to spare the children the trauma of parental conflict, in my experience the courts are more swayed by the pattern of contact rather than by these “excuses.” The wisdom of Solomon does not apply. 
A divorce can get complicated if the parties have property (real estate, automobiles, vacation property, pensions, jewelry, etc.) or minor children. Usually, the divorce can be done more quickly if the spouses agree on how to divide the property and handle custody and parenting time with the children. Many cases start out with a lot of disputes, but then the parties are able to reach an agreement. Parties often reach agreement after using alternative dispute resolution (ADR) services outside of court. NOTE: If you feel threatened by or unsafe with the other party, you may want to get legal advice or help from an advocate before using ADR.
