If you asked and he told you no in some provable way (email, text, with disinterested witnesses) and you made your plans after that, I would set all of that out in an email and let him know that the children will be with you BECAUSE he told you he did not have plans. Then the burden should be on him to go to court if he wants to make a big deal of it. Good Luck. If you don't have proof, you may have a "he said, she said," and you may have trouble.
