Advice for young relationships?

Danielle • I`m 17 years old.. I enjoy Art, Food & Jeeps. Want to be an O.T. one day. I`m super in love with my boyfriend Michael.❤️
I've been dating my boyfriend for two years. We've been best friends for fours years. I'm only 17 years old, but I love him so much and think about our future together. I really want to make this work. Anyone have advice or stories for me about their relationships at this age? And if they're still dating their significant other from high school?
