You’re not being unrealistic. If Gillian and P were really together, for ‘some time now’, as anon said, then she would have spoken about him by name at least once, been seen somewhere that isn’t staged at least once, acted at ease, happy and normal all the time, behaved like his girlfriend, and posed for happy pictures at events (not pictures where she looked like she would have preferred to be digging ditches). Gillian and Mark were confirmed. She almost always posed with him on red carpets.
