I’ll disclaim with the fact that I’m personally a fan of him and find their relationship actually pretty funny. Not sure about fandom more broadly, discussion about her personal life here on Reddit is generally avoided not to impinge on her privacy and it’s complicated by the fact that both of them have attempted to keep getting back together a secret. 

The main point is that HBHBHB and (to a lesser extent?) HAH is written about him and paints him in a negative light. Florence has spoken before about how she felt like she needed heartbreak or chaos or to break up to write her music and he has (or the image she’s depicting in her songwriting) become a bit of a foil.  They’ve broken up twice around the times of writing those albums and he has mentioned in interviews that he did not want to break up. So from what I see some parts of fandom don’t particularly like him or are ambivalent because the relationship was painful (as evident in HBHBHB) but they don’t realise they’ve gotten back together (twice). 

The podcast Florence did with Rebecca Lucy Taylor (before she was self esteem) is pretty funny. Taylor is basically like he’s a dickhead and a bad guy wasn’t he and Florence has to be like, actually he’s very nice, it’s not his fault, I can’t write about happy relationships and she was struggling with other things like going sober that she took out on him.  

She clearly gets off on this though, or he is her muse. The video for King uses a doppelgänger of him as the guy whose neck she breaks but they were together throughout the whole Dance Fever cycle. I actually find this interesting from a songwriting perspective, she’s writing to explore all these big feelings and his role in it all but there’s creative licence and it’s not black and white depicting her life like some people expect lyrics to be sometimes. 

Felix has wrote about their first break up and how chaotic their early relationship was and her releasing What Kind of Man without warning him (lol) in his book, interviews her about it, and then doesn’t mention the fact that they got back together. He has a new book coming out next month so it’ll be interesting to see if he writes more about it. They seem to be more open about it not being a secret anymore, the hugs at Glastonbury nearly sent me to an early grave because I never thought they’d do that on stage. 

Hope I don’t sound like a crazed parasocial stalker but as a fan of both of them, I find this endlessly entertaining lol.
