My partners son is 6 soon and my boy is 5.
So for the last 6+ months his son has been calling my son stupid, everytime we see them. We see them every 2 weeks.
With the added 'I hate you, I'm going to put you in the bin and I wish you were dead', at least every 2 months.
His dad's way of approaching the situation is mostly just saying his name, when he says these things because he continues to say them after his dad will then say 'that's not nice/kind'.
It isn't being resolved, I mentioned it months ago (not to brutally and just that he needs to address it). But now told my partner in a more brutal way that I will not accept it. And mentioned how he needs to address it by telling him why ita not ok and that he will not tolerate it.
This is now bullying and I can't handle it, it's causing way to much stress.
I don't really know how to handle the situation on my behalf, like he's not my child I shouldn't be telling him off etc...
But I cannot have this going on anymore so I'm at a lose, and feeling that the relationship is really not going to work anymore.
