Ds has spent Christmas with his dad, I was talking to him on the phone tonight and ex told ds if he's naughty he will throw me on the train track. Ds was very upset, I was saying to ds daddy was being silly and of course he wouldn't but ex was saying "if you're naughty I will". This was as he was putting ds to bed, so my poor boy will be lying there terrified. I feel sick, just want to go and grab ds (ex lives 300 miles away). Ds is coming home tomorrow, but I am so uncomfortable with what ex has said. Ds is scared! WWYD?
