Could I be reunited in paradise with a woman whom I loved and she died before marriage?

I love someone more than i love myself and she did the same. She would even cut her fingers before someone else will see her nails except me, we were more dedicated than someone could imagine.So we were trying to get married as soon as possible. My family and we two were ready to get married but her family hasnt yet agreed and mentally tortured her. However, she died recently. The heart i have given to her, i cant give it to anybody else not even in hereafter or in my dreams.The immense love we had, cannot be described even if i write thousand pages. if i really remember the things of this dunya. And people do not forget these things. If we two go to jannah, can i not marry her there? Im decided not to get married again, i will rather slay myself than marriage. And she is the result of my dua of whole ramadhan. I could feel every bit of it. No way on earth that she isnt the result of my dua of every fasting day. And a single dua is accepted while fasting in ramadhan, theres a clear belief in islam. And i heard loved ones, especially someone couldnt marry because of death will be reunited in jannah. Can someone give me any proper hope? Im doing good deeds so that she and i, both go to jannah together and i decided to isale sawab a part of my sawab of my whole life. Cause she is not in jannah instead she herself was a piece of jannah, my soul. I can never decieve her, not in this dunya,nor in the afterlife. She have her life as a proof. I must prove it too. I know we did wrong but we didnt do anything bad. I kept it pure.kindly give me proper hope. I beg someone
