The person ending a long role may need room to feel relief and loss together.

Two opposite feelings can be true at once without either being a lie. Ending something long, a job, a period of caring, a role in a family, can bring genuine relief and genuine grief in the same hour, and people often assume one must cancel the other. It does not. Both are accurate reports on a thing that was heavy and also mattered.

Give yourself or somebody else room to say both, without a follow-up question about which is really true. And be patient with the way they alternate rather than resolving, since that is how these things usually go.
