I though at 1st it was good, but when I go halfway to end, I feel almost puked for that last part, totally gross for that 180 degree personality.
I prefer him on 1st part before accident than become retarded who like do violence on girl and going rough sex like that.
I would prefer to know whether the personality change was mainly due to the accident, or as a combination with the accident and the fact that his 'briefly girlfriend' might've started cheating on him while visiting, thus hindering any mental healing process.
