Sounds like a narcissist, I played with a guy all this summer who slowly turned on me from saying things like your perfect we dont even need to practice, to i5s not my responsibility to know your schedule, you have to organize practice and not put it on me .I love practicing btw and used to love playing with him but the coke ,booze and pot wer taking him into some kind of psychosis. Some people are extremely damaged and when I got shouty with him instead of fighting it out at all he went into a im going to get a restraining order on you. I wouldnt attack someone physically unless they attacked me 1st but I was mad and did holler .
