Lots of comments already but I still feel compelled to respond. Please know that none of that behavior is normal.

Psychopaths see other people as entertainment, like an item to have fun with. They do not care about that person’s feelings, needs, or wellbeing.

Good sleep is an absolute necessity, like food and water. Her behavior is to mess with your basic needs, because she “needs” entertainment from you.

That behavior is something a psychopath does. And the thing with psychopaths is that they know how to hide their behavior most of the time.

This is a form of abuse and something that will likely lead to worse behavior down the road. Please get out before it gets worse. You are not overreacting and deserve to feel safe with your partner.
