Help:/

I’m 15 and my boyfriend is 16....my parents do not like him because I met him from a friend, we’ve been talking for 1 year and FaceTiming. He is legit because he shares stuff about his family. He’s not cat fishing me, and when I told my parents abt him, they reacted bad:(. They said he could be a catfish, but I didn’t tell them that we FaceTimed. I have lots of pictures of him and it’s on Snapchat, so it’s real time..how can I tell my parents? They thought it was sneaky!!! I feel like shit for doing this but I really do love him. We live one state away, and he even uses the snap map! He IS legit. Help!! This is tiring..
