The speaker is a man who gets endless compliments. Friends, relatives, strangers and even an ex call him smart, funny, kind and hardworking. People wonder why he's single, and some want to set him up with their daughters. The list at the start is almost playful, with each quality tied to a different person, but it grows into a pile of praise that starts to feel heavy rather than flattering.
The last line changes everything. After being told he could make anyone happy, he adds "Everyone except her." That small phrase suggests there is one particular woman he wanted, and for her none of those good qualities were enough. The line "I, wanting to believe" shows he longs to trust the kind words, but her rejection outweighs all of them. The mood is quietly sad and a little bitter. It's the loneliness of being admired by everyone while failing to win the one person who matters to you.
