A new possibility does not have to make the old loss feel unimportant.

Something good arriving after a loss can feel oddly disloyal. Part of the mind treats the two as competing claims, as though accepting the new thing were an admission that the old one mattered less than you said. A person can be missed exactly as much as before and still find that a Tuesday in June is pleasant.

You do not have to wait for the grief to shrink before allowing something new. Let them sit side by side, without asking either to make room. And if guilt arrives with the good moment, treat it as a sign of how much was loved rather than as an instruction.
