It's hard to answer a question with any of the facts.
You may not like what you hear once you get your answers but that doesn't mean the advice is wrong, bad or that anyone is out to flame you.
I am assuming from your quesiton thus far, that you don't like what you find online about the emancipation laws for ND, most likely this is not the answer to your situation anyway and are hoping for someone here to give you a way around them. It also sounds as if your boyfriend has violated some court orders and that you have some responsibility in all of this, thus the way you feel. We are here to give you advice, not everyone here is an expert, so don't get angry with the advice you receive that isn't what you want to hear and dismiss it or be so quick to accept advice that differs from the majority of responses just because it is what you want to hear. The decision is still yours, you bear the responsibility for your decisions in life.
That is why we need information, the facts, your ages, what happened.
Sometimes parents, including step parents have your best interest in mind even if it is not what you want at the time. If your boyfriend respected you, he would not break court orders meant to protect you, trust me, you will feel differently in a few years and wish you had listened.
