How can i block my boyfriend's psychotic step mother on facebook if she blocked me?

[IM†GOD]

ask your boyfriend for her email.

do you delete history often or ever? look through that if not

make a fake facebook add your bf and then ask to request friend from the mom. take her email and use it to block from yours.

on fake say your his friend or something (or pretend to be new gf to make her happy since she doesen't like you, then she will be pissed later)
