We fell In love and we wanted to get married. Can I be very clear there was no haram between us! He was murdered, will Allah unite us in jannat?

I met a man whom I fell in love with and he loved me too. We did not make a haram relationship, instead we waited so he could buy a house and marry me. We did not see each other a lot because we wanted to do it the right way. I last saw him just before he was murdered. I miss speaking to him and I feel sad that he is gone because he was the only person I had in my life that genuinely loved and cared for me. My question is, will we be United in jannat?
