Harriets advice? What advice? I must have missed that post. (I'm now reading back through it because I feel like I've missed something here)
WTF people. We're making this up as we go.
We don't know the reason she stopped wanting to see flex and yet somehow it's been decided Harriet is to blame.
"Ooh, she didn't reply to him therefore it
must be because of Harriet."
I can be as understanding and supportive as anyone, but I won't blow smoke. Yeah, Harriet doesn't sound like the most pleasant person, but does that automatically mean she ruined things?
She appears like someone with strange priorities (an ex's ex) and someone who likes to make a fuss of said issues. In this case it interfered with your date (thanks to your good intentions earlier).
I thought PF had rules on being overly speculative...
