I think it's about someone the writer (Alex?) met who really wants to be friends with benefits. At first, she just wants to be coy and play hard to get, but then realizes later that she really does want him/her. But by then, that person is in a relationship, hence the lyric "You found somebody else/And it's tearing me apart". Then she decides to let it all go ("Dont come looking for me), realizing that they were just manipulative.
