From my understanding the lover of the one singing the song is jealous, angry, etc. and don't know that they're actually their heaven in hiding, and the person singing the song understands the abuse or neglect, and knows they can easily take away the relationship, or the person understands their 'lover's' jealousy, and doesn't want to talk anymore, like the lyric, "sitting on the concrete in your basement, but I don't wanna start a conversation." ( or something like that I'm on a tablet ) They just want to leave the relationship, while the lover tries to find ways to get them back.
