No it didn’t mean that much to her cos she was settling with him. But when she walked back into that villa and saw he was sat there with someone else, she realised that he had also been settling with her
and it stung her ego. Her ‘aha!’ moment was, ‘so what was that note all about then?’ cos she had caught him out. He had been laying it on thick with her knowing all along he hadn’t actually been fucked about her just like she wasn’t particularly arsed about him. He was being a complete phoney with her. He was saying how much happier he was since being with her and how he ‘hadn’t stopped smiling’ and the lads were all agreeing with him. So I get why she was thinking ‘what the fuck was all that about then?’
