Dear Prudie,
I’m due to run into my ex at a networking event. She left me for another man and I have no interest in rekindling things with her. I don’t see the point of pleasantries either. Since we broke up, I’ve shut her out of my life, not returning her emails or texts. I’d love to tell her what I really think of her, but our bosses will be there and it isn’t the right time. The last thing I want to do is to give her the idea that she can somehow have friendly conversation with me, in person or by email. Is there a sure-fire way to keep conversation at a minimum but also to convey that she should get lost, and stay lost?
