Dealing with a Spouse with a “Mild Cognitive Impairment”

My husband was diagnosed with MCI in 2019. He is pretty independent, just forgetful of time, dates, location of places, anything electronic & events from our life together (we’ve been married 52 years). It’s all just getting to me. I find myself wanting to be alone so I’m not continuously reminded of these changes. Because my friends/family are out of state, working, or involved with their own families, I really have no one to talk to so I’m seeing a therapist twice a week to deal with the sadness, anger, grief I have over his condition. I just wonder if other women find themselves in this position & how they are dealing with it.
