Happiest, you sound really stressed out about it. Your friend probably feels that there is no way of really knowing whether this family member has stopped or not since you don’t monitor him 24/7. You only know that he stopped with you.
Please don’t think that he doesn’t care. Maybe he cares too much and just can’t handle the pain it causes him to know that you were hurt so badly and still carry the baggage with you. Maybe he fears that you will always carry the baggage until you report him. But don’t for one minute think that he walked away and doesn’t care. He might feel he needs a break because there is nothing he can do to help. It is not easy being the support system either. I know. I am up many nights because my mind does not shut off while I think about those who have come to me with their issues and I worry about how I am going to help them. Abuse has a rippling effect.
