I don't even think it's intimacy we need. Attraction is what's needed.
Most women suddenly get VERY attracted to a man who walks away with his head held high knowing and realizing that he is a "great catch" and that he not only DESERVES a woman who is mad about him, but will GET one..
Your own lack of self confidence in what she really is giving up is what is holding back reconciliation. LET HER GO.. YOUR CHOICE.. YOU be the letting go leader..
MAKE her chase you... You have NEVER given her the chance to see how she really feels about you.. Give her that freedom and give her that chance. Hold the line. . Show her a man who chooses NOT to be with a woman who isn't attracted to him. They both deserve better.
