Hello
@Dutchman
It sounds to me as if you are inflicting the suffering you feel your wife is experiencing on yourself.
I believe your wife is no longer experiencing the suffering she endured before going into residential care and you are allowed to take pleasure in simple things without feeling guilty.
I say this from my own experiences. My husband was so contented in his care home and so well looked after, the burden for his care was lifted when I realised the care home was doing a better job than I could at that stage.
It doesn`t mean I started to live the high life. I visited on alternate days and we enjoyed each others` company much more than we did when he was at home with me and presenting with challenging behaviours.
Meanwhile I got on with my life. My husband was still on my mind and in my heart but I knew I had done the best for him.
I know you are unable to visit as you would wish because of the virus but this is not your fault and feeling wretched won`t make it better.
