She is always going on about Wilf! I feel like for some reason in the last year he’s always coming up and it‘s so odd. She acts like that was her ‘big’ relationship from her 20s, the one that some girls have that messes them up or defines them for a long while because they had shaped their life and emerging adult identity around them for so long, talked of marriage and moved in together, etc. But that’s not Wilf for her, her big ‘young adult’ relationship would be Alfie. Wilf isn’t even like super young first love either, it’s just a random ass pretty short relationship from when she was what, 19?
I wonder if she keeps thinking back to the demise of her relationship with Wilf because she realizes subconsciously that the choices she made right after that were a reaction to the breakup, like her going for Alfie and everything that followed. So she keeps going over it trying to work out her mindset in a way.
