Just jumping in to say that I really like your brain. :) And omg, I hadn't quite put it like that to myself before, but yes, she dumps an entire ten year relationship, one that clearly matters to her a lot, for a maybe with Philip. I just. *incoherent flailing*

Oh and I definitely think Philip lied mostly on instinct and also because he wanted to have his own secret to get back at her a little with. My current theory is that he rationalised it later to himself as not wanting to put their relationship to that particular test right at that minute, but I think he'd be wrong about that.
