Dear Queenie,
After my ex and I broke up he started going with another girl who is a little younger than I am. I don’t care about that, but she seems to think that because I lost him and she has him now, she can tell me what’s wrong with me and give me advice about everything.
I don’t want to make a big thing of it because we have mutual friends that I don’t want her telling lies to about me, but she’s really annoying.
Queenie, how can I get her to lay off me?—Annoyed ex
Dear Annoyed,
You can listen, nod pleasantly, thank her, and ignore what she says. Or you can just walk away when she starts with her criticism and/or advice.
Or you can tell her (as pleasantly as you can manage) that it is really none of her business and you are not interested in whatever it is she has to say.
