You are doing the right thing by leaving her alone. She already knows how you feel...believe that! There is NOTHING that you can say or do that will bring her back right now...so pursuing her will do NO GOOD. You've already seen how it pushed her away even further! She will have to come back on her own...plain and simple. You have no control over the situation. So don't try to control it! You are being told the right things by the people here...I know it's hard to accept that...but it is what it is. Many of us here are in the same boat...our spouses left us too. Get stronger, get better, be a better man and a better father.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
