Have Relationship Questions? Ask a Counselor for Answers ASAP
This is Dr. David
I am sorry about your boyfriend.
dating you is no excuse for what your boyfriend did to your sister.
you need to break it clean with this boyfriend of yours.
it sounds like he has some power and control issues if he is able to rape your sister.
your sister needs to be checked for pregnancy and also report her incident to the police.
she needs a gyn examination as well
you and she will both benefit from talking to a psychotherapist or a counselor face to face about this event
let me know if you have questions.
