Mine did this exact thing.
2 days later I got a can we talk call
Last time she came in was Aug 24, within two hours I had a message saying basically that she came in to wish me a happy birthday.
This time I've not received anything from her. I think she now realises something, that SHES ENGAGED, and thus I'm not interested.
I would hesitate even to use the term "mine" nowadays, as she's nothing to me but a bloody annoyance.
