Same here. OK, apparently there were texts quite a while back where she said they could go to rehab together, they needed help, etc. However, I think that was more proof of her wanting to establish power over him than a genuine desire to help him.
What I found really appalling was her reaching out to his Mom and other family members after the suicide repeatedly offering condolences, etc....stressing she was his girlfriend. Plus, that charity event gave me the creeps....more attention-seeking b.s.
