Are there any ladies here who can give examples of traits of the attractive strong guy that seems to be what women are looking for?
I asked my wife for you. She said girth.
Aside from "girth" (nice one steve), CONFIDENCE!!!!!!!
The confidence to move on with your life and make decisions and be assertive and stop being approval seeking and being emotional, take the lead role in your life, determine where it's going, don't let someone determine this for you.
She let you go, great! Follow that instead of pursuing her.
You have been given notice.
Move on, in the opposite direction, holding on to her is going to insure that you don't get her.
