Sounds more like a kink or a fetish, rather than her being a “vampire”.
So, how do we conclude her behaviour and how do we resolve this issue? Maybe we should find a common denominator that most succubus/incubus entities share, but that’s like looking for a specific needle in a huge stack of other needles.
They are strong, persistent and powerful individuals with knowledges of a variety of areas such as magic, psychology, physiology, energy manipulation, creation and destruction. They are also dedicated in a way that some of them expect that the human show the same dedication back to them, hence the risk of jealousy to occur whenever we lack dedication towards them.
When they promise you commitment at your own request, they will give you that and some of them expect to get the same commitment from you. Very few humans have the guts to commit, because we get bored when relationships gets settled on a daily basis. So, instead of doing something about “boring routines”, we break up and give up on the relationship, and that’s something these spirits have a hard time to understand. And I can agree and even understand their frustration about human relationships to some degrees.
I would say that she’s a strong willed individual that doesn’t take shit from anyone, including yourself. Who wouldn’t want a woman like that!?
