3. Call your boyfriend from somewhere he won’t be able to see you.
“If there’s nothing going on, he should just answer the phone normally. The important thing is to make the conversation as normal as possible.” With this approach, you can investigate things from a safe distance. Sometimes he might not answer if he’s doing something work related. In that case, ask him why he didn’t pick up later. If he lies, you’ll know he’s cheating. By using multiple checkpoints like this, you can gauge your boyfriend’s reaction and get to the bottom of things.
