Please help me. X just emailed 15 minutes before scheduled dropoff to say he broke down an hour and a half away, he is out of reception, that he will be back late, and is keeping S2 overnight. My parenting plan isn't legally enforceable. I'm really worried. I responded asking for the location so I can pick S2 up and that S2 isn't prepared for an overnight stay. X isn't responding to my call, text or email. What do I do???
