Addendum:
It's that or they'll ditch because they've waited and waited and waited for you to stop pretending and to be "just like everybody else", i.e., lazy, complacent, thoughtless, careless, forgetful, selfish, and so when you didn't, it just made them more nervous. Eventually resentment built up in their minds, and they began sniping at every little thing, real or imagined, trying to "find you out". Then they begin reading it all into you because they have to, for their own ego's sake.
^^^ Then they leave/ditch, and they blame you for it and will tell you all of the things they "knew about you from the beginning", i.e., the stuff they read into you, and it's pretty ugly.
