It's crazy how love can make our common sense go out the window sometimes.
I've seen people post about how they haven't heard from their POI in a year or more, yet still believe readings. I am NOT judging here, just saying, if you were to tell anyone that situation, they would probably want to smack you upside the head and say wake up...but here we are, getting readings and believing them when there is no indication that the POI is even slightly interested anymore. I've even read stories on here where people have said the POI got married to someone else while they were waiting.
I'm also not saying a person can't come back after a long period of time, the real question is, do you want to wait? When is enough enough.
