“Meaning yes, he pulled her (with authoritative force) by the hand to bring her out of the room (as she & he explained me) and which resulted in her hitting the door frame, but he wasn’t aware she had hit her head on the door frame because he was leading her out of the room, while facing the hall, pulling her out with one hand.”
In other words, he pulled her so angrily that he had no idea where she was nor what she was being slammed into. But by golly, she was going where he wanted her to go, regardless of her health and welfare.
ARFWS, that may have not been intentional, but that’s not an accident. He was out of control with anger. He needs help.
