There is a guy that i have know for +2 years . He is 18 & will be 19 in November & i will be 15 in October . Him & I have a on & off relationship but I don't know if this is right . I have been talking to him for years & want to introduce him to my parents but i'm scared of what they would say . But I love him so much & just don't want rejection if I tried to introduce him. I have never met him in person , we have seen each other in public but never have tried to meet up or anything like that. No sexual things have been said or done . Please help me on what to do .
