As with relationships, friendships can end for a multitude of reasons. But unlike relationships, we're less likely to talk about the cause of their demise. Films and shows like Tuca & Bertie Broad City and Booksmart have championed the highs and lows of female friendship. But for better or worse, it can lead us to ask too much of each other – expecting the other to plan a frankly outrageous hen do , or not wanting to admit you're fighting over a boy because it feels like a sexist betrayal to call another woman out. The reality of friendship – where a lot of us don't have one single best friend who fulfils our every need but a sprawl of interlinking people who all have different values and faults – is much harder to fit into a TV show, but can leave you feeling wanting. And trying to let someone go can feel like a betrayal.
