My husband and I have been in our relationship for nearly 21 years now, only 3 of which have been as an actual married couple and that mostly because I have pushed for it from the start I believe. But, the last 6 months or so, I noticed something that my husband used to pride himself on no longer exists and I am not sure what this means exactly and would appreciate some outside perspectives on the situation i guess is what I am getting at. He used to pride himself on the fact that he was as he put it “tuned in to my voice” meaning like I could be in another room or a conversation with someone else and he would still hear every word I spoke. But, lately, I have actually had where I am literally sitting next to him, saying his name, and he has no idea. Like sometimes, he won’t even believe me that I had been trying to talk to him before I would finally get his attention, and even get aggravated that at that point i have no desire to repeat what I had been trying to say prior to that. For reference as well, I am 39, he is 48, so chances that it may have something to do with age dont have much bearing in this situation either. I would love to hear some others weigh in on this situation if possible, it just feels like a big red flag to me and I want to see some others weigh in perspectives before I stress out too much about it. Thank you for your time and opinions here, I really do appreciate it.
