That's a little dramatic...and weird.
How can you have not spoken to either of them for that long? You seem very immature, this kind of thing happens a lot to a lot of kids. Sometimes people just stop loving each other and they become miserable together. So if they are able to survive independently from each other, they break up. I'm 19 too and i could never see myself cutting my parents out of my life for something like that. Family is too important to me. What a lonely life you'll lead without your family, i feel sorry for you really.
