I'm in the process of separating from my husband. He is currently looking for somewhere to live and in the meantime we have each been spending time away from the house to give each other space. I live in London and last week I went to stay in Manchester for 2 days for work as we have offices there. Usually i stay in hotels but last week I stayed with a friend who lives nearby, and the week before i did the same. Last week, I called home to speak to our children and he asked questions about where I was etc. I gave vague replies as no longer feel i need to be held accountable for every move. He then relayed my full movements to me while I was away and the previous week - how I'd worked at a house in x Street, gone to the office the following day, returned to the house in the evening etc. He says he got this information from the messages we've sent to each other. We only use WhatsApp but from all the research I've done, I have no idea how he's managed to get this level of information. I feel freaked out and don't know what to do next. Aibu to think I've somehow been tracked? How do I get it to stop?
