Bro Death:
Your ex is trying to have it both ways:
1. Dumping/breaking up with you,
2. No being lonely.
She can't have it both ways. I'm afraid if you allow yourself to me used, you'll get used.....life is like that. Unless she is still giving you bjs, which you don't mention so i assume it is not the case, then this will have to end. Just tell you you can't talk, you're deep into a computer game or something.
The sure fire way to end it is to have your ex find you with a new squeeze and your tongue deep you your new project's mouth right in front of your ex....she won't call you anymore after that.
Having said all that, maybe deep down inside you LIKE the fact that she still calls you.
Anyhow, there it is.
