"Now the ex is 'wanting the old 'me' back and said.. 'that's what I've been waiting for'..."

Hi Hippyhoppy
He left YOU, my lovely, and he wants the 'old you back'......and says you've been waiting for it?
Have you?.......do you want him back?
As for the guy who's unavailable, is he married maybe with kids?
Unless he's having troubles with his own relationship, there will never be a chance with you.
Woofgang's advice is mine too. Find someone who wants you and you them the same way.
Best of luck, hh x
