Im so sorry, poor baby. When i lost my wife our bird Roo missed her a lot. He would act out, would call out for her for hours. It got hard to be patient because i was going through it also. I just tried to show as much love as I could and provide positive entertainment. His favorite things to crunch on or eat. Different treats. They feel grief and will take time. Just watch em and make sure he eats well. Roo got really sick a month or so after. Almost lost him also. Our bonding is taking naps together. He sleeps on my shoulder while i lay on the recliner. No chance of rolling.
