I think she's actually coming out of retirement. Her profile disappeared in October and now seems to have suddenly reappeared. The retirement sentence has just been replaced with an update that she's on vacation until January 8th. Some logic in there somewhere no doubt.
Reading between the lines I got the impression she'd decided to become a full time lesbian, but perhaps student finances have dictated otherwise!
I saw her a couple of times and really liked her. One of the most middle class girls I've ever met, and it was nice to have some intelligent conversation. Lovely petite figure, and although only a fairly vanilla service, she was very enthusiastic and genuinely seemed to enjoy herself. Have messaged her in the hope of being able to meet again soon, but no reply yet.
