Toxic implies blame on both sides doesn’t it
It just struck me, @Justwondering3 , that it doesn't imply blame on either side. That's quite different from it does imply blame on both sides.
It's quite hard to define the difference, but can you see what I mean? I'm sure judges have to say a lot of things in impartial ways, and I imagine this was one of them. If the judge had said that you were in a 'damaging' relationship, would you have felt that that blamed both parties, or that one was the subject of the damage and one was the object? I think it can be seen like that, too, with toxicity. Your ex was dishing out the toxins, and you were receiving them, so you were both part of the toxicity.
If the judge said that the two of you were in a toxic relationship, I don't think any blame was implied at that point. The blame came later, when s/he started detailing who had done what.
I don't think relational toxicity and abuse are on a continuum, as in 'it's toxic until xyz happens, and that's the point where it becomes abusive.' I think all abusive relationships are toxic, and more has to be said to ascertain where the toxins come from.
The judge wasn't talking about a non-abusive relationship, so I'm not sure that's part of your question. What's toxic to one person might not be toxic to another, though, so it'll be pretty hard to define.
