So she's in love with this guy and will always find an excuse to write to him to convey her feelings. But she's afraid to own up to them for the fear of blowing it (it's her way of protecting herself from heartbreak). So she's stuck on it, while all her friends (including this guy) are happily moving on with their lives.
In the second half of the song, she is in another phase of her life where the distance between them has got bigger. She is dealing with the whole thing, pretending to have moved on. But she can't, because fact remains that she was, is and will always be in love.
