I'm married and love my wife. But the watch I wear regularly was a gift from my first girlfriend when I was 20. My wife has complimented it several times and assumes I bought it myself.
There is no romantic attachment left. My ex is basically a stranger now. I just genuinely like the watch, and it has survived nearly 15 years. Still, every time my wife says it looks good, I feel a strange discomfort. Objects can outlive relationships, and nobody tells you what you're supposed to do with them.
