Could also be that Kamila is giving Dima enough rope to hang himself with,so she goes along with his neglecting behavior to see if he will change on his own.She pretends to be really happy with him because she knows if she complains he will temporarily change his behavior in order to hold on to her.After an extended period of neglectful behavior she may just one day bluntly say I gave you the chance you wanted and you didn't change,so good-bye. Remember Kristy told Kami to not give him an ultimatum,because that would cause him to alter his normal behavior.
