in the forest, under cherries in full bloom

To me the sentence "he found himself thinking that the sky would fall” (p.201) could be interpreted in the following way:it seems as if the man was able to see the future, the events which are depicted on p.204-205. The sky falling is a reference to the sky of cherry trees in full bloom, which is all you can see when you look up in the cherry forest (For spread out above him, as far as he could see, were clouds of fully opened blossoms" (p.204)). The constant falling of the cherry blossoms is all that you witness. The man decides to kill the woman but for a moment stops and thinks "If I kill her, will I be killing myself?" (p.201), which is what happens in the cherry forest, first he kills the woman, and in turn he himself vanishes from earth. Furthermore, after "the sky would fall" (p.201) it says that "he felt terrible pain, as if someone were choking him" (p.201), which is in fact the exact same thing he felt the woman doing.

For me the excerpt “Even now, no one knows that secret of the cherry forest in full bloom. Perhaps it was loneliness” (p.205) represents what the man has went through. I think in actuality he was able to find out the secret of the cherry forest. If the secret is loneliness, then it is what the forest does to us. While being under the cherry blossoms, people cannot escape from themselves, they go crazy. For some, it is the purest form of loneliness. Being on your own, surrounded by nothing, you have only yourself to reflect on. The man didn't like pondering on things. He would leave it till next year. The hopeless situation left him to see all the flaws in himself. 

my question is : how do you interpret the existence of his wife? do you think she ever existed? and what do you make out off them disappearing amidst the cherry blossoms.
