I think that the line "you will never come close to how I feel" is a sort of double meaning. At first, it sounds like this solitude is such a nice feeling, nobody could ever experience that feeling. But to me, it seems that it also means he doesn't let anyone get close to his true feelings, leaving him in complete solitude. So because he loves the solitude, he won't let anyone get "close to how he feels."
