I have to admit, I wasn't able to read all the texts, but I read enough to say it was more than her telling him to drop dead.
This isn't a thing where she got sassy and told him to go kill himself and he went and did it. This is a long discussion where she repeatedly asks why he hasn't killed himself yet, telling him that he had the perfect opportunity and that if he couldn't do it then he probably wasn't going to, telling him how easy it was going to be once he put his mind to it...
It's ****ing horrible.
