I was recently talking to a friend about that delusional bitch.... I asked him if Will Smith is aware that she changed over the years and that she essentially lost the plot. Because apparently he seems to think that he's married to the shy girl from the block.
Anyway, my friend said that Will Smith is most likely fully aware of it, but doesn't want to give up on her, close the chapter and move on. Once the door is closed, it's closed forever.
That would at least explain Will Smith's irrational behavior. The studios just fired him from all future projects.
