Depression - an understandable side effect of being a LBS - puts a big damper on libido and general enjoyment of things. If you're feeling "meh" about dating, evaluate whether you might be depressed.
If not, then it just might be an unwillingness to be vulnerable again.
In my case, I will definitely say that having a healthy libido was a driving factor in getting me out there dating.
As for the question of people coming out of the woodwork - well, for me as a woman in her 50's when my ex left, it wasn't exactly like that - BUT - I did notice men more and as a result, they seemed to notice me more. I think when I was married I just didn't look at other men and must not have given off any vibe of being available.
