My W told me she used to ball and beg her mom not to send her to her dad's for court ordered visits. My W had to fly by herself as a minor as her dad lived out of state. She hated going. Unfortunately, that is part of D. If your H won't let him text you, barely lets him call or FaceTime you, then I'm assuming you're husband will not agree to but making him start overnight? You could talk to him about it, but if he refuses there isn't much you can do about it.
