My ex keeps showing up to see our son when he feels like it. He does work shifts during the week but not at the weekend, I think he should be spending time with his son but instead he will show up in the late afternoon stay for an hour or two then go. He doesn't take him out, or do anything with him, when he goes he says he doesn't no when he will be back and he will see our son as and when. To me it feels like everything and everyone is more important to him that his son.
