Supporting a self-punishing host
My system has a rotating trio of hosts, one of which has a history of physical self harm and addiction. I'm usually the one who takes care of these things, but he took on important insurance related task we've all been putting off because I've been struggling lately. When we realized we missed the due date, he immediately hurt himself and gave up. I'm asking about this here because this means getting professional support is delayed.
I freaked out and we argued. His point of view is that it's his body, so he should be allowed to do whatever he wants with it, and this is how he keeps himself in line so he can be functional. He thinks that because he's not doing anything "dangerous", it shouldn't matter and I should just not front if it bothers me.
My argument is that it's my body too, I don't want to be hurt, and I care about him as both a part of me and as a person. I tried to remind him that he wasn't even conscious at the time of the due date. He has no memory of us doing anything insurance related and couldn't have stopped this. If it's any specific alter's fault it's mine and our other host's I was co-fronting with then, but he won't see it like that. I think he still views himself as the "main" alter. I don't know how to get him to comprehend that there's no such thing when he already understands that our other host and I regularly take over for weeks while he's dormant. I'm guessing it's to avoid feeling like he has no meaningful control over his life, which I do sympathize with.
But I know how to fix the insurance issue and he will not let me do it. He wants to wallow in a mistake "he" made instead of let the part responsible fix it. Forcing him to back off might make his issue with control worse but if we lose access to our medication, it'll hit him the hardest. I'm not really sure what to do here, but I don't want him to feel like this is a major setback because he's made so much progress recently. If you have any advice or insight, I'd love to hear it.
