@Akikako Doesn't matter, their relationship currently is bad. She knows, that's why she doesn't consider themselves lovers. I would not mind either of them, if they prove to be the one that can help her. Because if she continues like this it's only a matter of time before she kills herself.
It really is a strange phenomenon, people who 'brag' about how much worse they have it and not-so-subtly fishing for sympathy/attention on the internet from complete strangers.
His friend honestly seems like a better option than both of them continuing what they are doing.
I doubt she would take it well if she found out about the truth.
