SERIOUSLY I NEED HELP!!!?

i have a ouija board... iv played with it literally 1000 times and nothing has ever happeed to me before (i believe that if u know hw 2 use it safely it is fine) well i was playing with my ex about 2weeks ago i asked if anyone was there 2 talk.... nothing happend i was ready to put it away when i noticed i herd my bf whispering something and it began to move... i asked him what he was saying that the board was responding he refused to tell me... every question i asked the board replied no... then i asked for a name ant it spelled out R-A-N-Z... (my bf was still whispering to it) and it spelled out "Soul Possession"..... after that he asked if we could put the game away so we did and i asked him what he was saying to the board and he told me he called for a demon to come and apparently it worked.. i looked the name up on the computer and i found nothing... a day or so later he claimed 2 see a face in the mirror when he was in the shower... he started seeing (infrequently) shaddows... then one evening he was over my house and we began to kiss, he started to touch me and i told him no and all of a sudden his voice got very serious and deeper and asked why should he and then started to refer to himself in 3rd person and calling himself names and saying that our breakup was the key for "him" to takeover that if "he" couldnt have him noone would... then he left my house well i walked 2 lock the door and he was standing there as if he was knocking on the door and had the most confused look on his face.. he asked why he was standing out there ... he remembered nothing about the previous events... as he was walking later he herd 3voices in his head saying "if i cant have you noone will" "i will kill you" he almost got hit by a car then shot by a gun that same night..... he kept seeing shaddows and almost got hit by a car a day or so later... i was just talking to him about or relationship and he told me that he has been having dreams where he sees everything that he has done (that he could not remember) its like he is standing next to himself as he talks and does w?e he does..... he tells me that he doesnt want any help but i know that it will onmy get worse if i dont help him i just dont know what to do.. & thats a shame for me because i know alot about this kind of stuff any help on anything? who? what? where? when? why? n how to get rid of it???
