I am so sorry to read that all of you have been sick except your h. I hope you and your family are feeling better today.
Your h is in deep replay and is still looking for the fountain of youth. No matter what he tries, he's aging each and every day...poor man! Fix whatever you want and have the aroma drifting around the home. He's mouth will be watering and it won't take long for him to want some of what you've prepared. LOL!
As for him being in his room. He's either sleeping, on the computer, listening to music or just staring at the 4 walls. They can be very content being in their safe haven. For us, this would drive us nuts...but not them.
Please take care of yourself and I do hope you are feeling better.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
