I have found in my experience with men, that men that are interested in high school girls have severe issues. I think it would be better to put that relationship on hold until you are in college or out on your own. Even though that is only a year away it will change you completly. My friend did the same thing you did and basically played house and mom to his children. She enjoyed feeling like a grown up at first but started to resent the man immensely for making her grow up to fast.
