Anger is just such a severe stage I think of grief but one that you just have to work through. It's basically yourself trying to convince yourself that there's an easy way out. When it doesn't work, we have depression, perhaps the longer stage of the breakup and the most acute where you just feel shit. But in another sense, I think it's actually can be quite nice and a little bit indulgent in a good way to just let yourself be sad. Let yourself really be sad about what could have been, about what you miss about that person.
