Actually, I don't believe that if you die you would get the chance to be with the one you love in heaven because eventually our souls will undergo in a process called reincarnation. This way the soul could have a second chance for another life to fulfill his or her unfinished mission in some other way and a different life which is not related to the first one, but the efforts and the things he/she does will be accumulated to test their souls for another purpose, and that is to love over and over again.
