What should you do if your mom found out about your secret boyfriend?

Come clean, and try to work out any consequences, or problems that might happen after. She was probably in the same position you were, and if you lie once, or hid something from your mom, you are just going to have to start hiding more stuff, and lieing and lieing. It will soon become a habit. Therefore, just try to work it out, and try to make her understand from your point of view, of how you are probably reposonible, mature and committed enough to have a safe relationship, and that you would not disobey some of her conditions or rules. Good Luck! Hope this helped.
