Am I wrong for cutting my ex-gf/best friend off ?

i dont know whp's wrong because there's not much to go on ....But have you not been speaking to her ??? If you haven't let her know why ....just be honest there is no right or wrong you guys both feel a certain way about the situation .......But just tell the truth and if you really value the friendship with her you wouldn't allow it to end on such a sour not ....i hope this helped
