Grace and Ash really are exhausting. It’s just a mismatch.
I don’t think either is necessarily in the wrong totally. I do think Ash has some dubious attitudes to women, but many women don’t seem to mind that. Grace does, but she seems to get upset and frustrated, which lands badly with Ash and makes him defensive. She’d be better off laughing at him and saying ‘that’s not going to get you laid, Boyo.’ Just - get your message across playfully so he learns without feeling attacked. Maybe?
But he’s also being quite dramatic about saying he needs to change his entire personality. He doesn’t. He just needs to say ‘Oh shit. Yeah. Sorry. I see how that came across. I didn’t mean that at all. I meant I find YOU attractive.’ and then they both drop the nonsense and move on. It’s not a big deal.
All of which is completely irrelevant because they are incapable of doing any of that, don’t match and need to give it up now. They don’t seem to have any bloody fun anymore.
