she stood up and began striking him in the face.
From what I see, she never striked him. The point where you claim she is striking him on the face is only her getting up and extending her arms. It might be anything from trying to strike him on the face to an angry push. Pushing someone that you think is trying to push you? Yes reasonable. But for anything more than that, It does not seem to even provide enough evidence for a reasonable belief of anything more than a shove.
