Ok, enough is enough with his demeaning, blaming, stupid emails he sends you. There is no reason for him to email you about this stuff. If you have a schedule set, end of story. Do whatever you have to do to stick to the schedule, no more flexibility until the "battle". It just gives him more chances of twisting the truth, and building up "ammunition". Talk to your lawyer, but possibly send one more email stating that you are going to stick to the schedule from now on because you refuse to submit yourself to his verbal abuse and accusations. Then, stick to it. I know it may be hard with the kids' schedules, but I think it will be better this way (legally) until things are more solidified. His behavior angers me, and I don't even know him.
