Hi, my husband's ex wife moved to a different city, now he could only see his son on Christmas or New Year depending of the year and half of his vacation. This year he got for Christmas and his school brake is on the 18th, but his last day of school is on Friday the 15 now he wants to pick him up on Saturday since is a 5 hours drive to go and 5 hours to come back, but she doesn’t want him to pick him up on Saturday she wants him to go on Monday since she knows that he works. What my husband should do?
