No. It is never a good idea to date while you are still married. Until you have a final hearing on your divorce, you are legally married. Dating another person could affect your divorce. For example, if you are entitled to alimony, it could reduce the amount of your payments if the judge finds that you have fault in the divorce.
Furthermore, your judge will be unhappy if he or she finds out that you have taken your minor children around a new boyfriend or girlfriend. This could affect your parenting time or visitation schedule with your children. Courts will consider the character of anyone living with you or anyone that frequents your home.
