A possible yandere is the least crazy of the yandere family and is normally not thought of as a yandere. I mention them here because yanderes typically start at this stage. They are the jealous girlfriends that you see in TV dramas. Possible yanderes will not resort to (extreme) physical violence, but will use abusive language against rivals in love. They are also very likely to grudges against people for the rest of their lives.
