It's possibly (probably?) coincidence, but two or three times in the past couple of years, my husband has said something very specific that I'd said earlier that day on whatsapp. Both times it was in a chat with my sister, I think.
On each occasion it was when I was relating the whatsapp conversation to my husband that he then said something specific that my sister and I had said to each other in that chat.
I've nothing to hide, so I'm not concerned about him finding out something, and if he is tracking me I can't imagine why - our marriage is fine.
My whatsapp account isn't linked to any other devices but mine, but is it possible for him to somehow be monitoring my phone and / or laptop? I couldn't find anything online that would explain it, and there's nothing I can find in my devices (I'm pretty tech-savvy). Is there some kind of malware that can hide that your account is linked?
He doesn't have any kind of contact with my sister, he hasn't even seen her in years as we live abroad and I tend to visit on my own.
It has to be a coincidence doesn't it? The examples were so specific though.
