Amy Marie,
Sorry to hear of you recent struggles. We tried to start a thread for spouses but it did not develop much of a following.
The needs of wives is much different than that of parents and other caregivers.
The best solution for many is to find a brain injury support group that includes support for caregivers. Here is a link to support groups in Pennsylvania

The event with his loud conversation with his father is a classic cause of a return or increase of symptoms. I wish I had a suggestion on how to avoid a repeat. The dynamics of extended family and their refusal to understand his needs is a problem in itself that just magnifies the PCS issue beyond your control.
I hope you can find some contacts in the support group network that can help you. At least, you can be with people who understand you situation.
My best to you.
