I think Binky is waking up to the fact that she was a bit of a sh1t with J.P. it was interesting to see her two closest friends taking sides with J.P. on this one. And i think the whole truth between Binky and Julius is yet to come out.
She did say to her mum that she misses J.P. Its sort of like she cant live with him because she jumps back into her old lifestyle and she cant live with him because she is not ready for commitment.
