A woman messaged The Wake Up Call in what she describes as an "urgent DM Dilemma". She explained that her and her ex have been co-parenting just fine with their children. However a problem has emerged and it just so happens to be around the time that she told her ex that she has a serious boyfriend. She's about to leave on a work trip and she needs her ex to take their children a day early. Originally it wasn't a problem, but now that there's a boyfriend in the picture her ex wants an itinerary of her plans while she's gone. Should she have to give him that info?
