Does losing the person you thought was your forever get easier?

Im in my late 20s and lost the one person I truly thought would be in my life until the day I died. The love I have for this person is so unique and I truly love them with every bone in my body. But it didn’t work and now I wonder…

Does it get easier? Will I meet another unique love? Or will they truly be someone I miss every day or hurt thinking about? I know it’s raw and that impacts pain but what if this was it…?
