This has always been my general thought for this song (thought it was the only possible interpretation but guess not), but anyway: the singer (Draiman) has a lover/wife whom he loves, but he falls for someone else hence mistress. He's struggling with both relationships because he's sincere about them both, but both of them are cold to him and get his feelings all jumbled up, almost like they're playing mind games with him. He hopes he'll get through to at least one of them but he never does, so both relationships seem like a dead end.
