This isn't going to be a popular opinion, but here it is.

I would be very offended if my husband had serious concerns about my behavior and had not gone to ME about them before he went to others. If he had tried and I was not receptive then that's different. It seems like decisions are being made for this woman before she is even formally diagnosed.

If someone came to me and described such behavior in their significant other I would say to ask them to go to a psychiatrist or other qualified medical professional for a proper evaluation. I would feel like I was gossiping about the person in question unless they knew and was okay with their partner discussing it with me.
