NAB - have lurked and read all your threads about this guy and just wanted to say that I am in a very similar situation to you where I am finding it near impossible to stop texting even though I know I must, otherwise I am just prolonging the agony
I have found the following very helpful:
When I really can't resist the urge to text, I write the message I want to send, then instead of sending it , I save it to drafts (sounds mad I know but has really worked for me)
and
When thoughts of him pop into my head, i look at the clock and allow myself 2 minutes to think about him and then I force myself to banish all thoughts. I have found that it is getting longer and longer between thoughts of him.
Really really feel for you because I have never felt pain like this.
