Scary

My boyfriend is older then me. I'm 15 almost 16 and he is 19 almost 20, our birthdays are 2 weeks apart. My mom and dad love him like a child lol and are very supportive. But I'm kinda scared because I know people would try and get us in trouble. We have been friends since I can remember and we love each other very much. We don't have sex because we agreed to wait till marriage and I trust him fully. Any advice on how to handle people that are very rude and hateful toward us. We don't care if it's illegal we know we are right for each other
