Really?
Some have suggested that he was a high maintenance, manipulative, possessive creep who was harassing and e-stalking this poor girl and worse.
The very fact he offed himself tells us that he was mentally sick.
Can you not see her POV?
I also suspect he didn’t intend to die. He may have been trying to get her to do or say something, or to come running... to convince her he was serious and she’d better do this or that... I think there’s a very good possibility that he played chicken and lost.
