Doesn't sound as if it was much of an actual relationship to start with.
He didn't tell her where he was really going on his birthday ( probably so she didn't turn up there herself), he didn't tell her he had a daughter until near the end of the so called relationships
I a sure he mentioned to her that he had only wanted her to come over for a couple of hours and not the full weekend not long after they were both in the house, at the time I thought it was just a hanky panky type of thing going on.
