How do I tell if my home or car or computing equipment is bugged? I am asking as I have a suspicion my ex is doing this. He has been extremely controlling in our relationship and today told me something that I have only mentioned to one person using almost word for word what I said. It’s possible this person went to him but when I asked her she denied it and looked totally surprised. This is the only other option. I was in my car on the phone when I was talking to her. Any advice gratefully received.
