ohhh i see <| sep |> I agree OP , regardless of what his actual diagnosis might be , he ' s clearly not a good friend to you and possibly a toxic coworker , who could harm you professionally blame you for his own mistakes or undermine your work , for example . I know it ' s hurtful to lose a friend or have to let one go but it ' s less damaging in the long run than hanging onto a friend who batters you emotionally and destroys your self esteem . Maybe be polite to him as always but not engage with him on any deeper level than as a coworker . You need to protect yourself from his hot and cold , erratic treatment of you . <| sep |> She didn ' t ask anything ! She informed you of HER long time plan of giving them to you when you ' ve finished studying .
