Good post, Hunny. Is there some way that you can let you sister know that this person is not OK with you, even if she doens't know about the abuse, that you would rather not have anything to do with him and you shouldn't be alone with him, maybe even go home early if he shows up? Maybe if you can talk to her about this, you can work out a plan for how to make sure that you are safe the whole time. Good luck
