I Know Him So Well (with Sheridan Smith)

Nothing is so good it lasts eternally
 Perfect situations must go wrong
 But this has never yet prevented me
 From wanting far too much for far too long
 Looking back, I could have done it differently
 Won a few more moments, who can tell?
 But it took time to understand the man
 Now at least I know, I know him well
 Wasn't it good? (Oh, so good)
 Wasn't he fine? (Oh, so fine)
 Isn't it madness he can't be mine?
 But in the end, he needs a little more than before
 Security, he needs his fantasy and freedom
 I know him so well
 ♪
 No one in your life is with you constantly
 No one is completely on your side
 And though I move my world to be with him
 Still the gap between us is too wide
 Looking back, I could have played it differently (I could have played it some other way)
 Learned about the man before I fell (I was just a little careless, maybe)
 But I was ever so much younger then (Younger then)
 Now at least I know, I know him well
 Wasn't it good? (Oh, so good)
 Wasn't he fine? (Oh, so fine)
 Isn't it madness he can't be mine?
 Didn't I know how it would go?
 If I knew from the start
 Why am I falling apart
 Wasn't he good? Wasn't he fine?
 Isn't it madness he won't be mine?
 But in the end, he needs a little bit more than before
 Security, he needs his fantasy and freedom
 I know him so well
 It took time to understand him
 I know him so well
