Brief background. Ex was abusive. Wasn't allowed to see DS for 4 years until he completed a DAPP. He's still displaying abusive manipulative behaviours. Impossible to co parent. He's not allowed to contact me so handovers done by a family member. Family member is non confrontational which works but its hard when I need to raise an issue. The issue at the moment is that his dad keeps buying him toy guns. Not colourful nerf guns, but fake black machine guns that would look real from 20 metres away to the untrained eye. I've said I can't control what he does when he's with him but he needs to take the gun off him before he comes home. Regardless, he's been sent home multiple times with one. He then pretends to shoot me with it and says he's going to kill me. I then get paranoid that it's a message from his dad because he knows how I feel about it. I'm also then the 'bad guy' because I'm the one talking it away.
Am I being ridiculous? How do I deal with this effectively?
