wowww thats a really hard question and i dont think that bella would be very deeply in love with anyone from the series but she would eventually find someone. this is a really hard question to imagine the answer to in your head so sorry, but i don't have a very good answer
she probably just would chose a boy. she wasnt looking b4 they came so i think she wud just wait til the right guy came along. she was never drawn to any1 in the books except edward and jacob
well it would be no one because she would be dead but if she did live she would probably be single for a while as bella is diffrent form other people and she just closes everyone out of her life but then in the end with all of mike persistence she would pick mike
