I found that actually quite disturbing, that she felt she needed to give him a (or another) Xanax for anxiety when he was showing no signs of anxiety. If anything he was trying to make himself heard and get his point across.She was controlling him in my view.
Yes, I understand this view but I would say there's no evidence that she was pressuring him to take it. It sounds as if he was already using it to stay level during what must have been a stressful conversation, and I think there's also a history there of her reminding about his medication as well as trying to help him stay 'clean'. She appears to have taken a bit of a caretaking role in that way which apparently was appreciated at times. They obviously both have quite a range of prescription drugs they use more or less legitimately, so I see it as reflecting that dynamic.
It doesn't say much for their relationship obviously if that was necessary in order to have a conversation but that does tie in with her witness statements that basically they couldn't have a productive conversation about any difficult issue. Anyway, I would agree that on the basis of that conversation he seems far more level-headed than she does. The evidence seems to show that he's a very different person depending on what substances he's been ingesting.
She is explicitly saying she is violent towards him.
She is, but my point remains that there is a wider context which may shed a different light on that dynamic. Not to suggest that it makes what she's saying/admitting ok, but abusive relationships are complicated. So I think we need to look at the evidence as a whole. And I think he's obviously aware of the recording and perhaps making statements in light of that which may not reflect the entirety of their relationship.
It can tries to deescalate at times, but that it doesn't necessarily follow that he's always so reasonable (and there is at least one incident - in the plane - that pretty much prove that as far as I'm concerned with the texts between her and Nathan somebody). And as I said, some of her accusations are really terrible. I have no idea how well evidenced they are but that may become clearer over the next couple of weeks. They may be untrue, but if they are true then that puts him firmly in the abuser role as far as I'm concerned.
