It was clearly just his way to get with someone else..using that as an excuse (as saying 'oh you are hotter than her so I am done with her' wouldn't go down well
). However when it became quite clear the new girl wanted nowt to do with him, he had to backpedal with his 'It's what I do, I run away when a woman gets to close' rubbish
Rosie is such a twat if she believes it all tbh
