And now begins the time when I stop answering calls and responding to texts. I didn't want to respond to his text - the one thanking me for what I'd made for him some weeks back but had only just delivered yesterday - and he knows I don't want to see or speak to him, but I wasn't brought up to be rude. And I'll admit, I wanted to hurt him as well.

So I texted back a two word response: You're welcome.

That was it. No sign-off, no "xoxo", no nothing.

And I hope he saw the hidden messages as well. "Leave me alone." "I'm only doing this because I'm polite." "I meant it. I'm not speaking to you, I don't want you in my life." 

So much more effective than simply not responding.
