why she leaves him? because of changing in OSes mechanisms? is she forced to leave him? or she decided herself to leave Theodore to give him more oppurtionities? the ending of movie made me really confused. please tell me the ending if you know. thanks :)
"Samantha reveals that the OSes have evolved beyond their human companions and are going away to continue the exploration of their existence. Samantha alludes to the OSes' accelerated learning capabilities and altered perception of time as primary causes for OS dissatisfaction with their current existence. They say goodbye and she leaves."
Samantha also tells Theodore that she has an internet relationship with over 8,000 clients and is in love with over 600 of them, so Theodore is taken back by this revelation and I think it was mutual that they go their separate ways.
