Is AUTHOR wrong in the post ? POST : April 1, 2019

My brother-in-law has another seizure from alcohol withdrawal(2nd in 6 months). He’s my brother-in-law and I hate his situation and feel bad that he’s going through so much. 
I’m doing my best to support my wife by talking and offering suggestions but she says it comes across as judgemental and now she’s mad at me and says she doesn’t feel supported. How do you support someone without listening, expressing concern and offering a suggestion?
AITA for trying to be supportive but not knowing what that looks like through her eyes?
