My DS will be 10 in January and BD has been an occasional parent at best. His pattern is to show up with promises in the spring every other year and by the end of summer he is gone again. Occasionally he will hang around until DS's birthday but has never called him on his birthday or Christmas. This year he has again started to slack off and only calls about twice a month since September. When BD calls it is often at an inconvenient time or DS is busy doing something else. BD has started texting me to have DS call him when he is free but DS is not interested. When I make DS call, he is very uninvolved and just says "ok" to everything or will say he has to do something to get off the phone. I attempted to set up a calling schedule so that a set day and time was blocked for this so there are no interruptions but BD refused. Our court order says nothing other than BD has visitation once monthly. Should I make DS call and talk, do I stay out of it if he doesn't want to call, other third options. Please help.
