I had a semi relationship with my dad (abuser) as well for years. I never told him what i remembered. I felt he would kill me. I never told him i am in therapy. I finally stopped contact with him 2 years ago. Eeven though the relationship was strained, and i "harped" on some of the more blatant aspects (physical, emotional abuse) he still cannot understand why I "the bad daughter" refuses to speak to him; "the best dad in the world who made some mistakes and said sorry for them".

If your friend is of legal age, i would probably encourage her to support herself in therapy without her family's infringement.
