It's about the church's oppression of gay people. If you watch the video, all the men are dressed provocatively and attached to strings like puppets. The strings signify the hold that the church has on gay people. If you replace "She" with the idea of church or religion it makes more sense. She pretty much explained it all very recently. It has NOTHING to do with ex boyfriends. Right before she sang the song she made a speech about how if Jesus loves everyone then that should include gay people. She said that God is non-judgmental therefore the church should not be. It's a statement against gay discrimination.
