Aaliyah, I know how complicated your problem is, but don't take things so seriously. Move on with the flow of time, no one has seen tomorrow, so do whatever your heart tells you or whatever seems right for you today. Who knows it will prove to be a right decision in your case? While telling your parents, make sure you give them enough hints beforehand, so that they wouldn't be shocked. In case of changing religion, I don't think you can completely abandon your present religion, because you were in that religion or culture for more than twenty years I guess. And trying to change or forget your root is almost impossible. I met a Nepali female doctor about three years ago, who is married to a Pakistani doctor. They fell in love when she was studying medicine in Pakistan. When I met her, she said that she had just returned from Nepal after celebrating Tihar and also said that she was thinking of keeping 'barta' on that day but couldn't. I wondered what that 'barta' was about, but realized later that she was talking of Ramadan fasting. It was good example of religious co-existence. I think her husband wasn't intolerable to her original religion and not so strict to maintain her new religion(that's why she could miss her fasting). So, if your boyfriend is understanding enough, he should allow you to continue your original religion even though you adopt the new one and display religious fraternity and co-existence. If not, you should think about it again and try not to fall into the ditch of religious bigotry and blasphemy.
