It doesn't matter
/It doesn't matter, so let it go. And once you let go, forget about the fact that you let go. No sense in wondering where it went either or how it took this long to release what is no longer serving you. There may be all sorts of valid reasons why. You need no justification. No sense in worrying about why it was, seemingly, of service to you. Enjoy the feeling of releasing the who, what, when, and why.
