Thank you for your replies and honest feedback! I feel like I should elaborate, though I'm not sure how much of a difference it will make-- the misunderstanding was that earlier last week, I had privately reached out to the wife of the couple that my husband and I are very close with about some fears and concerns I had with some impulsive decisions my husband made recently. I ended up telling her more about where he is in his mental health and more about his childhood trauma as we discussed his actions-- I had thought that that was okay to do with her because of how vulnerable he has been with them in the past. However, when I eventually told him about my and the wife's conversation, he reacted very poorly and felt betrayed because it crossed a boundary for him/broke his trust in having a private conversation about him that we were going to keep private even though they are as much his friends as they are mine. He felt that we intentionally isolated him and broke his trust in the conversation about him that we were not planning to loop him in eventually and that, if anything, she was encouraging division/separation from him (the latter is not true as much as a paranoid trauma response, I think). In our conversation, he made it very clear that his issue was not with my reaching out to her privately, and he would still encourage me to reach out to support. The issue was that my and the wife's conversation felt like a betrayal of trust because she has been as much a friend and support to him as she has been to me. Not sure if I'm making this clear. But, essentially, he wouldn't have had as much of an issue with keeping this conversation from him if I had reached out to someone else that he had not put so much trust in. After our discussion, I could see why he felt like his trust was broken, but when he confronted the wife about this situation, she doubled down and said that she didn't think we did anything wrong. And then she started to call him out on his toxic behavior in a way that only further triggered him and basically forced him, in his trauma response, to not want to give her and her husband access to us anymore.
It's tough because the reason I had reached out to her for support was because of how close they were to us both and so had more context and knowledge of his mental health and background. And they have shown us so much support in the past too. But I see how with how things have escalated, he can't get the support he needs from them currently without being majorly triggered. He has explicitly encouraged me to reach out to others for support-- both my therapist and others. However, it's just an issue of who do I go to about this when I had been leaning on this couple more so in the past due to their knowledge of the context and my husband's situation. Also, I can't help but wonder that once I do start confiding in someone else, if my husband would at any point make me cut off ties with them too if he feels threatened by them in some way. (I think he has an underlying trigger/paranoia of people wanting to take me away from him)
My husband knows he needs help. He has been diagnosed with PTSD, BPD, Bipolar, and anxiety. From what I know of his childhood trauma and what I've read, I believe CPTSD is more accurate than PTSD. He started trauma processing with his therapist a few months back. And, just earlier this week, before all of this blew up, he expressed his desire to start an IOP. He knows what he needs to confront and work on to change. I'm just disappointed because I thought this couple would play a big role in supporting him as he started this program, and that doesn't seem to be the case anymore. Even though I'm personally still figuring it out, I do believe I can find support elsewhere and that he won't stop me from doing so. But I don't know if that's temporary and if in the long-run, this toxic pattern of cutting me off from people who are concerned for my wellbeing will progress. From this incident though, I also now see how important trauma-informed support is because the way the wife reacted (though, I do believe came out of genuine concern and care) only exacerbated the trauma response (and, in hindsight, I see how she's done that to others in the past too).
