Hi Craig
You need to decide, I think, whether you are going to get in touch with her, if only to gain closure, or just deal with your feelings until times helps to put them at the back of your mind.
A break-up is like a bereavement, so it will be difficult, but I really think that all the ploys that you were using, at first, just made things worse. Do you agree?
I know that you thought that you were doing the right thing ~ and that you were being advised to do this, but straightforward communication is usually the best thing.
