kundera's identity

i just finished re-reading milan kundera's novel, identity. the main characters are a man and woman, jean-marc and chantal, and the story is about the ups and downs of their relationship. chantal feels that nobody is attracted to her because she is getting old, a fact she shares with jean-marc, the man she is in love with. then comes a series of anonymous love letters for chantal, who hides them from jean-marc as she tries to discover the identity of her unknown correspondent.  when she finds out that jean-marc has written the letters, she feels that he has violated her privacy. jean-marc, on the other hand, feels enraged by her response to another man, the writer of the letters, who is, ironically, his own creation. 
it's a brilliantly written novel about two people,who at their most intimate moments, feel that they do not recognize one anothers identity, that their voices come from far off, and that each moment of life bears the option of losing one's loved one.
i am a massive kundera fan, and this book, the second time around, was just as hard to put down as it was the first time i read it over ten years ago. 

"...no one can do a thing about feelings, they exist and there's no way to censor them. we can reproach ourselves for some action, for a remark, but not for a feeling, quite simply because we have no control at all over it."
