I started dating someone who told me they'd been single for about 18 months. Various things (I don't want to get into what they are but pretty damning stuff) are making me think that this isn't the case and his "ex" is either a. still his gf or b. they have broken up but it's more recent than he's claiming/they're still living together for practical reasons.
I want to message the ex to confirm they're broken up. I don't want to know any sordid details. Just a simple "yes we broke up in X" will satisfy me. FWIW, I'd never message her behind his back. I have no interest in doing that.
He doesn't want me to contact her because he feels like it's a breach of her privacy, which I do sort of get. However, I wouldn't give two hoots if my ex's new partner messaged me to confirm when we broke up. I have nothing to hide so I have nothing to fear kind of thing.
But is he right? Would it be unethical/unfair on her/a breach of her privacy for me to ask her the question? I have no idea if she knows I exist either way.
