<human>: Can you provide a brief overview of the text?

She told me that she loves me, and she'll never move on from me, but she wants to part ways after a decade or so. She told me she'll always love me, and we'll always be together in a sense afterwards and it isn't that she's breaking up with me. She just doesn't want me to have to see her die, or the other way around. She thinks it's best. I want to grow old with her.

Has anyone else encountered this before? I'm not really asking for advice, since I'm the only person other than her that really understands this relationship. I want to know if anyone else has been told this, and what happened.
<bot>: Girlfriend told me she wants to move on after a decade or so to avoid one of us having to die on the other. Is this common?
