How to tell a guy that you're not allowed to date
Ask your parents why.
You might be aware of your parents' rule, but not fully aware of the reasons for why your parents have this rule. Understanding why your parents have created this rule will help you explore your feelings, as well as communicate to your guy why you cannot date.
Parents create such rules because they are worried about your safety and well-being. They do not want to see you with a broken heart, or they might be worried about you being sexually active.
