You are getting a hard lesson in what it means to betray trust. I doubt your parents don’t want you to be their daughter. I do understand why they are so disappointed in you. Not only did you disobey their household rules but you apparently violated their values about when it’s appropriate to have sex.
I hope by the time you get this response, things have settled down some. You and your parents need to have a serious talk about values and rules. This shouldn’t be an argument. At 17, you are still dependent on them. Unless you are able and willing to go off on your own, you do need to graciously accept that they have more say in what you do in their home than you may think is reasonable. If your boyfriend loves you, he will respect your parents’ wishes and will apologize to them as well. Behave respectfully and helpfully and hopefullly you’ll be able to have a reasonable discussion with your folks about how to live together in a loving way.
In only another year, you’ll be out of high school and able to start an adult life of your own. At that point, you may make different decisions about how to live your life.
I wish you well.
