The great thing about LIVING is that we can always do better. Don't think of it as a loss, now you have a new opportunity to have even a better life. Take the good in you that was him and share it with another deserving person. Even he will appreciate you moving on and doing well. Remember you are in the middle of this life.... live it! Do you dwell on all of the other dumb choices you've made... I hope not... so enjoy your next breath... each one is a gift... don't poo poo tomorrow because yesterday was poop!
