I haven't got the book, but i have read loads of extracts from it on a sign up, so i get daily emails. basically if you're the boy, you have to do the chasing. she shouldn't ring you. but it depends on why you finished.
it can take between 6 weeks and 6 months to get an ex-back.
Flowers, letters anything romantic but you have to do all the work so she feel's special and so you feel like you have won someone special.
Hope this helps
If the other person called it a day then i wouldn't bother if your partner wanted you back they would of contacted you by now. If they haven't then id class it as over..
If you called it a day then do as dimwithwit Say's
But why i said don't bother if she called it day is something which Ive learnt and happens to be 99.9% true
As the old saying goes you don't throw your old shoes away until you have got a new pair..In other words she has someone else. This might not be true in this case but is true in most..
