As the custodial parent, am I obliged to transport my kids either to or from my ex's house on their weekends with him? I did at first because I felt guilty about the divorce, but now that all has changed.He can take days off because he wants to go to a hockey game,etc.. But he can't leave work an hour early to come get his kids.Also due to my guilt,I agreed to an unbelievably low amount of child support,can this be modified?It was only written in our divorce agreement how much it was to be.I live in PA.
