But have these people "let their exes go?". Letting them go means moving on, not having readings, not on this forum asking about things that people that haven't moved on have asked. If you've moved on from your ex, it means you've let them go and aren't interested in a reconnect anymore in my eyes. These people have taken their ex back or contemplating it.. That's not letting them go. Also, I'm not knocking Kristina but she hasn't really "moved on". She's still been posting and asking about Yona and the situation with her ex boyfriend at the time (which I want to make clear I am not knocking, it's upto her and she is a nice user who I don't mean this to come out the wrong way). Some people kid themselves that they've moved on, but it's like a dog with a bone getting bored. You keep waving the bone in it's face and pulling it away from the dog, it'll give up. When you throw the bone and leave the dog to it, the dog will go after the bone.
Sometimes someone will have moved on from an ex, and the ex comes back and they think, "actually. Why not? Let's see where it goes this time, if it has anything better to offer than before", but I think that that's different to some of these people who haven't moved on deep down. Sometimes we think we have let somebody go, but deep down subconsciously - we haven't.
