Lost connection

My wife tells me that our emotional connection is almost gone. I find it hard to hold a conversation with her on the phone, but my friends/ coworkers, I can be on the phone with for hours almost every day.

She doesn't work, she is a SAHM, so her day to day life is pretty repetitive, so she doesn't really have much to say. I try to talk to her about my work stuff, but half the time she doesn't understand or she can't hear me and gets upset or there is too much background noise.

She tells me the issues and how's she is feeling, and I know she is right about all of them. But I dont know how to respond, and she gets upset that I dont say anything. She's already told me she doesn't want to hear apologies, and im not trying to make excuses for it.
