The movie has lessons to be learnt
1. Don't make your whole life about just one thing - live, live out other aspects of your life because if he had done do she would have experienced other aspects of life with him but all they were living for was the "Gayle wind - battery" she didn't live she never lived her life - it was on hold waiting for the breakthrough of the battery and when it came he was with someone else that's what broke her - that's what drove her crazy.
2. Don't give up your entire life for anyone - they are humans and this get to decide what they want for themselves. Fall in love but live - have your social life, have your fun time,have every aspect of your life as you fall in love.
