Ugh, the whisper thing is brutal. My ex used to “take out the trash” for 20 minutes—turned out he was on the porch with his work “wife.” The “just a friend” line is the oldest in the book. Since you asked for something designed for calls/chats, I’ve seen https://spybubblepro.com/ recommended here before. A coworker used it when her husband got secretive—said the call logs with timestamps and deleted message recovery gave her the concrete proof she needed. No more guessing. It’s not about starting drama, it’s about trusting your gut. Hope you get the clarity you deserve.
