Boyfriend help.!?.?!?

Ok im13 going on 14 and I have been with my 15 going on 16 yr old bf for 3 months. I really love him. ( please no rude coments). Age is just a #. We hav talked and he has said that he won't have sex until he's married. We r both on all a honor roll at school. Have same hobbies. Same friends. ( were both unpopular.) we have a secret relationship because of ur age. Yet half of my grade knows. ( my friend couldn't keep her &@";/-( mouth shut.). And I haven't told my parents. My dad is very overprotective and virbaly abusive. He is 5 years older than my mom. But how do I tell them or should I even tell them. Please help me.
