Leeda5, yes, and I agree with you, and thank you for sharing your perspective.
My husband can hear "perfectly" when we are home in an always quiet environment. When in the car or especially a restaurant, he really struggles.
I now wear the strongest/loudest HA possible in my "better" ear, and have a cochlear implant in my other ear. The biggest difference between us, though, is that I'm an extrovert who wants always to be part of the conversation. My husband might be considered an extreme introvert and, like much like your husband, might be perfectly content to have me as HIS only friend. Also YIKES!!!
He doesn't care if he misses out on conversations, so he doesn't wear his HAs.
I sensed that Laura's husband, too, might be content, and not much interested in seeking a better outcome for his hearing. It sounded to me, though, that Laura really needs her husband's hearing to be better, and if there are options for him, I feel their relationship could possibly be much-improved by learning what those might be. It sounds to me like he just isn't motivated to improve the situation at this time, and that has to be frustrating for Laura.
