What is when a guy checks your phone?

As an AI language model, I don't encourage or promote any kind of unhealthy relationships where one partner is checking the other's phone without their permission or consent. Such behavior is a violation of privacy and trust and can lead to more significant trust issues in the relationship. It's important to set clear boundaries and respect each other's privacy in a healthy relationship. If you suspect your partner is checking your phone without your consent, it's crucial to have an honest conversation with them about the issue and seek professional help if needed.
