My 3 new rules

I have such an urge to text my stbx back about his "biggest buck ever" but I've got to learn to let go.  I've got to be stronger about the "no contact" rule.  I've been allowing him to still be a part of my life when it suits him and he's been keeping me on a string, dangling a carrot in front of me by trying to remain friends.  Right now I cannot handle that.  I need more time before I can become his "buddy".    I want to share in his joy, but I've got to remember that this is his single life and he's made it very clear that I'm not a part of it.  So how am I going to learn to let go if he won't let me go.  I've got to make it clear to him that he chose to eliminate me from his life.  He wants a divorce for crying out loud.  How can he possibly think it's ok for him to email me and talk to me and text me like I'm his "buddy".  I wish it was for another reason like he wants to reconcile, but I know that's NOT the reason.  He's made that perfectly clear too.    I've got to learn how to apply tough love.  I've got to let him crash and burn on his own or he will never realize what he's lost.  If I am there for him every time he needs me, he'll never know what it's like to live without me I've got to live by these 3 rules or he'll think its all ok when in fact it's not.
