Either that's a terrible photo of his girlfriend, or she's rather unnattractive...
She's not "ugly" as such, but I would imagine Marc could do better. Judging on looks alone that is, im sure she's lovely and all.

If she was a casual girlfriend, or the relationship was short up until this point, I wouldn't judge Marc too much for trying it on with someone else.

However, two years? living together? then going on tele to flirt with someone else whilst saying "there's a lot to say, isn't there?" and other people saying "it's meant to be"

Just awful.

Humiliating for Sarah, worrisome for Cerys knowing he could do that to a girlfriend of two years, and a horrible reflection on Marc.
