He sent her a "rosy wreath."
She sent it back.
He doesn't say directly how it makes him feel. He says that he smells it now, because it smells like her, and not like roses, so he claims that he's not disappointed, and that it actually worked out okay, because he has a special reminder of her.
I think he feels disappointed and is covering up, but I'm reasoning from what I'd feel, not from what he says explicitly.
