I understand your views and concerns. But I can assure you there is nothing wrong with my boyfriend, us falling in love was not exactly planned and as I said there are ground rules, we are never alone together. If we are in my room, door stays open. If we go out either one of my parents goes or I have to take a few friends and call my mom every half hour. We are not having sex and will not until we both feel ready and that time will definitely come after I am 18 or even older.
I can't really justify our relationship, I just know I love him. I suppose that may sound silly coming from a teenager to an older person, but its true.
I stand by my opinion that OP should tell the girl how he feels.
