Regarding Your Co-Parent Do I have to tell my co-parent when I am dating?You have no obligation to let your co-parent know about your casual dates.
Children deserve to be comfortable and safe in their own home.
When should I introduce my new partner to my children?
Most professionals agree that parents should keep their dating relationships private and away from children until the relationship is serious. What you should avoid though is introducing your children to every person you date after your divorce.
It is also critical that you remain in the role of parent and not turn into your child's best friend where you each gush about your new girl or boyfriend. Every child will react in his or her own way to a parent's dating after the divorce.
And as has been stated many times on this site, knowing your child will always help you better understand what may be going on for him/her.
