I expected these things to be like, they broke up and she was telling him to go fucking die or something. The same way people online go 'kys' if you pick Hanzo or something, reading those...jesus christ, quick 180 from 'you should get help' to legitimately helping this guy do it. Almost seems like she got bored in her own life and just wanted something crazy and exciting to ahve a 'story' or something.
Yeah sane individuals don't behave that way, and it certainly looks like she wanted a story to get attention from her friends (and or future relationship, playing the sympathy card). But I honestly don't know if she was on meds herself.
