Please, do not commit suicide! I know this seems awful now, but this too will eventually pass. I've been in this exact situation. I dated a guy for three and a half years in high school. After the two years my parents told me that it would be best if I were just to be friends with him because we didn't mesh well. (They thought we fought too much. Which we really didn't fight that much, but at age 17 the relationship was way to serious.) So we continued to date for another year or so. Eventually I realized they were right. But I loved him way too much to live without him. We broke up. But stayed close. We still did everything together. He still came to all my softball games. I still took him to school, and home from school. And we stayed close friends until I got together with the guy I'm married to now. He still texts me on my birthday and Christmas, but that's about it.
You obviously care for this boy. And every situation is different. If you have decided that you are going to just go through with breaking up with him, then the best advice I have is to be honest with him. Sit down with him and explain how much you care about him and love him. Then explain how your parents feel, and how much their feelings matter to you. That you wish there was another way, but that you do not like being dishonest with them. After all "honor they mother and thy father". He may be devastated, but he should understand. And you guys can stay close and still be good friends.
If you are going to stay with him, then you need to decide that and stick to it. Your happiness does matter too. And if its not meant to be, it won't be and your parents are worried about nothing. I wouldn't hide it from them though. Nothing good can come from that. If you have to tell them that you really like this boy (I wouldn't say love because most adults roll their eyes when their kids say love) and that you wanna keep spending time with him, then you should. Hopefully they'll respect you for being honest, and coming clean with your feelings. Hope this helps, sorry it was so long.
