False hope is worse than the truth, no matter how brutal it is. If that person chooses to return in the future, then that's all fine and dandy, but living on the hopes of they might is self-destructive.
On some level, I do agree with this. My feeling is that theres no harm done in leaving a door open for the WS to potentially walk back through later. The destructive behavior is sitting around waiting for that to happen.
In other words, lets say its a nice, sunny Sunday afternoon. Sitting in the living room all day staring at the open door, hoping the WS comes in is I think what you are describing. I agree, thats not healthy behavior. I would go so far as to say that staying home in the off chance that WS comes is also destructive. But, if you plan your day as you wish - maybe planting flowers, then going out for some lunch, and so on and so forth with the door open is OK.
However long you leave the door open is your choice. The key is to be able to leave the door open without focusing on whether or not she has walked through it.
