That’s When You Know

Well I've been up all night, a restless state of mind
 ♪
 Well I've been plannin' out how to make you mine
 Workin' out what I wanna say, a diamond ring for my last name
 When you can't let go, that's when you know
 I'll give everything for you, you just gotta say "I do"
 Through the thick and thin, you're everything and more
 Together we'll be standin' tall
 If the world starts to fall
 Would you walk with me through all the highs and lows
 That's when you know (that's when you know) (that's when you know)
 That's when you know
 We were laughin' at nothin', just wastin' time
 Holdin' hands, slow dancin' through the boardwalk lights
 Dark side on bended knee, you're tear-filled eyes lookin' back at me
 When you see your future, lightin' up your soul
 I'll give everything for you, you just gotta say "I do"
 Through the thick and thin, you're everything and more
 Together we'll be standin' tall
 If the world starts to fall
 Would you walk with me through all the highs and lows
 That's when you know (that's when you know) (that's when you know)
 That's when you know (that's when you know)
 Well, I've been up all night, a restless state of mind
 With a love this strong, you can't say goodbye
 I'll give everything for you, you just gotta say "I do"
 Through the thick and thin, you're everything and more (everything and more)
 Together we'll be standin' tall
 If the world starts to fall
 Would you walk with me through all the highs and lows
 That's when you know (that's when you know) (that's when you know) (that's when you know)
 That's when you know
