It depends on the person, I think. I mean, I didn't know the extent, I didn't know what he was capable at the time.
If I had known what he had done and will do or is doing, I never would have. Never. But he knew how to manipulate people so it wasn't obvious what he really wanted until the end. It was his specialty.
But no, my brother and best friend didn't hate me and were there for me. Then again, by the time they knew, it was over. After I realized the truth. The fall out was really messy. Really messy.
