My (ex) boyfriend wrote a hurtful draft email yet never sent it? mistake or intentional?

The bloke didn't have any true emotions for you because if he did, he wouldn't mind you bugging him or texting and mailing, take it from a bloke, we need reurance at times to, but try and stand tall to much, but leaving him to stew is a good thing because it now tells him your willing to move on, so if he does feel anything for you, he will come calling, if he doesn't, then take it as you have done your talents a big favor by not getting involved with a loser, which he basically is if you have made the effort and he hasn't, good luck,x
