I Must Be Somebody Else You've Known

Well, I used to be the kind of guy that didn't love a lot
 I took all the love they offered me with ease
 And it didn't make much difference if they loved me or not
 'Cause I'd love 'em for awhile then I'd leave
 Yeah, and I can't believe it's really me hurtin' like I do
 Just because you left me all alone
 I've seen it happen many times to other guys I knew
 Surely, I must be somebody else you've known
 Well, when I first met you darlin'
 You impressed me more than some
 I should have took the warnin' way back then
 But, I never stopped to think that
 That even my day had become
 And like the other guys
 I'd want you back again
 Yeah, and I can't believe it's really me hurtin' like I do
 Just because you left me all alone
 I've seen it happen many times to other guys I knew
 Surely, I must be somebody else you've known
 Surely, I must be somebody else you've known
