mom hates boyfriend.. help?

I am 15 and turning 16 at the beginning of october. I had my first boyfriend last august and we dated for two months until he broke up with me. He was informed he would need to have a very difficult surgery on his spine that I ,coincidentally, had about 4 years before him. He was concerned that over the course of the month he would be healing and kind of out of it from the pain meds, that we would grow apart. I told my

mother and she didn't believe a word of it. We remained friends and about a month and a half ago he told me he still had feelings for me, i did too. So naturally we began "talking", taking things very slow. School was over by this time and neither of us can drive (he is 15 too) so the only way i can see him is through my parents driving me to his house and vice versa. I told my mother about us being together again and she got furious with me, we argued and cried about it for two days when i had enough. She called me a whore and that i in no way need a boyfriend and a lot of other things. Another reason is that she hates him since he broke up with me. i haven't seen him in over a month and we miss each other terribly, i have no idea how to get my mom to see eye to eye on me with this. Help would be much appreciated.
