Shut the doors, and focus on keeping yourself warm for, the one who had to go has departed already. You have sent your prayers, the silent ones and the other louder than necessary to be heard and yes, he has heard them. There is nothing more that could be done on your side. Keeping the doors open won't lure him back. It will just keep you cold from the thoughts and apprehensions. You've got to move forward and the first step that's needed is to close the doors. You'll be the potential villan in the story but at least you'll sleep with peace of mind for yourself. Think of how life would be, even if you got him back, but would it be back to normal, as comfortable as the time when none of this has happened? Accept that things have not been well understood and recovery is going to be from both the sides. Unlike the rest of the times, you can't cover up from his side today. And you can't coverup the whole matter just by yourself. Accept. And close the door.
