The way I think about it: I'm willing to hold the punching bag for a limited time to allow her to de-stress. But she must not take me for the bag.
It is not my job to perfectly manage her. If she messes up her self care and reaches her limits there is only so much I'm willing to do. Consequences are so much better in teaching than I am.
Just that. I find myself suppressing my anger again to try to avoid conflict. But really, that's not how I should handle it. I only have a set limit on how much I can handle at a time and sometimes I can't handle anymore and that's when I need to remove myself from the situation emotionally and sometimes physically.
The only real progress I see is him calming down quicker and things being normal once more. But is that actual progress. I mean, I'm exhausted by the outburst and it takes me longer to recover than usual. And he's still experiencing so much dysregulation. Just because it's not directed at me, doesn't change that it happens.
I've made a ton of progress, but he's still stuck in old patterns, slightly improved.
