Three years of separation, three years of a broken marriage
It's interesting how both Shatov and Stavrogin had fucked up marriages, both wives named Marya. Shatov was the one who pointed out to Stavrogin that he had his marriage out of moral carnality. I guess it's because Shatov can sympathise - because he wanted his marriage to be good and normal. They have another similarity: Pyotr couldn't have them.
