There comes a point in a toxic relationship where you have to choose YOU over the past. Sure you may have “invested time,” but what does that matter if the person you’re now with is no longer who they used to be? It doesn’t matter if they WERE or COULD be who you want them to be. If they’re not NOW, then they’re NOT. You now need to think about why it’s so important to stay with someone who doesn’t appreciate your good qualities.
