Your best friend — the one you've known forever, who knew everything about you — has changed. New friends, new interests, a new way of being that doesn't include you the way it used to. They're not being cruel exactly. They've just... moved on, become someone slightly different, and the easy closeness you had has quietly disappeared. You keep reaching for the old friendship, the inside jokes, the way things were. But they respond like it's a bit babyish now, like you're clinging to something they've grown out of. The person who knew you best feels, suddenly, like someone you barely recognise. You're grieving a friendship that hasn't even officially ended — it just stopped being what it was.
