9. Invading your privacy, NOPE!!
In a healthy relationship, you do not need to hide your Facebook messages, emails, texts, or whatever from your man. But that does not mean your partner has the right to peek at this stuff once you leave your phone or computer open around them. They would be showing massive insecurity if they ever happen to do this. This behavior must not be ignored since it is a way of projecting their own issues and infidelities onto you.
