I get this question from people too, even though I'm only a few months post bomb drop. Folks ask "how come you're waiting around for him when he's done x,y & z?" Well, the way I look at it, is time passes regardless of what you do.
If you're sitting around crying every night over his photo while continuing to not set boundaries or letting him experience consquences of his actions, well, you're probably a doormat!
If, on the other hand, (as I am) you are still crying, still have the door open should he decide to recommit, BUT you are moving forward with life plans in case he doesn't, and working on yourself...well, you aren't actually stalled, or waiting or whatever. Time passes regardless, it's what you do with it that counts.
