Psychology works like this: people tend to live up to the expectations placed on them. If a woman believes that all men cheat, she will look for proof — checking calls, messages, and behavior. Over time, even a loyal partner will get tired of the pressure: some will leave, some will cheat, and some will simply shut down.

What to do? If the reason for negativity isn't the partner’s behavior but personal beliefs, it’s worth working on oneself. However, if his actual actions are causing concern, it’s important to discuss them openly rather than torturing him with suspicion.

Focus on what you want to see in your partner, not on your fears. Attention shapes reality.
