It’s possible that you are describing dissociation. Dissociation involves periods of disconnection from reality. It is a common response to severe trauma. It’s not dangerous per se but not being fully conscious and unaware of one’s surroundings is potentially dangerous.
One aspect of this situation for you to consider is that your girlfriend only “recently” ended a long-term abusive relationship. It may be too soon for her to be in a new relationship. She’s evidently dealing with the aftermath of the abuse. It is preoccupying her mind to the point where it’s sometimes difficult for her to function. It may not be in her best interest or yours to be in a relationship at this time.
You might be forgoing your needs which is not healthy for you and ultimately destructive to your relationship. It’s typically the case that one-sided relationships don’t last very long. You might be okay with not having your needs met at first but after a short while you may begin to feel resentment. It is good to support her but realize that a relationship might be too much for her to handle at this time.
It’s highly recommended that she consults a mental health professional who specializes in trauma. They can assist her in identifying whether or not these episodes are dissociative in nature and prescribe the most appropriate treatment. You and she might do this together or not; the therapist can help to determine the best type of treatment for her. If you have additional questions, please write again. Please take care.
