At thirteen, you recognize your mistakes and do not repeat them, unless you need to prove to yourself you still have a problem growing up and being acceptable of the penalties you brought on to yourself. The girlfriend is not going anywhere. She is still growing up too. See the girlfriend as a young woman and you as a young man. Respect her and her parents as you respect your own parents. Time is on your side. Be obedient and behave worthy of the freedom you desire.
