Since the answer is literally four words: She added him again.PS. I'll admit I don't know what the hell "readding" with a DD means, if this is some weird esoteric IB lingo, please enlighten me.
I'll have some fun and critically analyze every word she wrote.
Yeah I'll admit it was a bit crazy readding him (this means she added him back onto her friend's list, re-adding) and even talking to him after the threats he made. (this means she attempted to be friends with him even after the threats) He's extremely bipolar, and he'd act extremely nice and would be actually amicable and fun to talk to, and then he'd explode into mass-murderer rants or yell very loudly through text that nobody loves him. (literally what Josh does today. Josh acts like a child and has no restraint) I considered him a friend, and I guess I just forgave his weird outbursts because of that. (despite his threats, despite everything she called him, she still wanted to forgive him) He'd remove me at least once a week, and then readd me a couple days later. (Josh would remove her, probably after a rant declaring friendship over only to come back begging to be friends again. This is actually very common for mentally ill people) Sometimes I'd just readd him on my own, especially when he'd start telling everybody he knew that he was going to kill himself. (she probably felt guilt that Josh was suffering)
