Saying you're "peachy" simply means you're doing great. Sometimes you say it with sarcasm and thus meaning you really aren't that great and sometimes you can say it and really mean it. I haven't heard this song yet, but after reading the lyrics I'm wondering if the person saying life is peachy without her is really sincere...or sarcastic and trying to cover it all up. ;)
