Keep in mind - it’s the ones who are left that grieve, feel guilt, regrets, doubting themselves... Your boy is in a place where there is no pain now. But your family is right there, next to you. No one knows what tomorrow will bring. I would encourage you to focus your thoughts on the good times you’ve had, the love you gave each other, and turn attention to family. Doubting and reliving your decisions serves no purpose. You did what you felt was best for him at the time, and that’s as much as anyone can possibly do for our friends. We all would like to keep them around forever. But they deserve a good, happy life, not just struggling from one day to another because their humans can’t let go. The final act of love and devotion is probably the hardest one to do. You did it, and for that I am sure your boy is grateful. It’s time to let go, remember the good times from the past, and carry the memories into the future. My thoughts are with you all.
