struggling with a friend

hey i meth this some years back we became realy close,but latley hes been bullying me,and realy doing the worst things to me,im not sure why,when i try to talk to him about it,he manapulates the words and situations and kinda just ignores me,i realy trusted him with certain things and he realy caused alot of mistrust and trauma for me,he is also a sapposed holy man,or a spiritual leader,or guru i realy followed him with my life,he promised well being happyness,and truth,but all i ever since iv been followng him iv been suffering,i trusted him with my deepest problems and he realy hurt me,i even tried to commit suicide once because of the things he does it,now he realy did it for,like people who has hurt me in the past,some friend in the past that cheated on my gf at the time he's like bringing that up and its realy ptsd for me,i just dont think its worth it shouold i leave this person al together?

hes als blocking answers from me when ever i want a serious answer to a question he just ignores the situation
