I thought this was on the cards. I saw about three months ago, had a phenomenal time, but subsequent attempts to book her I noted became more difficult and her replies more sporadic. I felt there seemed a slight loss of enthusiasm. And no it wasn't me per se, as I tested by contacted her off different numbers. She was never rude, so this is not a criticism at all, just something made me think the enthusiasm wasn't quite how it was when I first contacted her.
JRC is right. It is pointless to speculate what has caused her to go. For us midland based guys, Michelle has gone, Hannah has basically gone, it is sad times.
