Gillian and David have chosen to live their relationship this way. But we do know for sure (because they told us so!) that they see each other outside of their public and professional joint appearances. Which is, so far, not the case with PM. Even if they’re not physically here for each other when one of them attend an event, you will notice that the other one very often, publicly support the other one. Also, if you look more closely at their whereabouts, you’ll see that there’s rarely a few months between the times they’re both in the same city. For example, when Gillian was the Globes, David was in LA. She has an event in early March in NY, when his tour ends. I look forward to see what she’s up to in February.
There are facts, I like to think that it’s more our logic that is trying to connect the dots, rather than our imagination making things up. Just take a look at last year timeline, there’s so many little things that can’t be meaningless. Unlike what’s happening with PM, which is, for now, pure interpretation.
