1 – we don’t know where she stayed. She has been photographed at the entrance of her hotel, but she had an appointment in there. It was not where she stayed at.
2 – she was seen in an airport, it doesn’t necessarily mean she headed to London. Even if she did, it’s fine, they’re about to have 5 months and a half being together 24/7.
3 – I agree, it seems like it’s their choice and I don’t mind. They’re more than fine with each other, so if they’re no longer comfortable sharing about their relationship on social media, it doesn’t matter. I’ll miss it, but I can live without it 🙂
