Hoping today goes by fast today. Thinking of you. Please have someone with you tomorrow when you are exchanging the kids, I would go as far as calling the police and asking them to just be there, this is something they will do if you let them know the circumstances. They would prefer to prevent something from happening then to have to come out after something has occurred. They'll just stand off to the side and not interfere at all unless he gets out of line. Please call your local police and arrange this.
