Exactly!
Go for it, if that's the life you want.
Put the whole titles and 'royal' thing behind you, it wasn't for you (and wouldn't be for many people).
Be Meghan Markle (or Mountbatten-Windsor if you want to take your husband's surname, not particularly feminist but whatever you choose).
Embrace influencing and celebrity, whatever that brings in those terms of success and failure.
But stop hanging onto the trappings of royalty (Empire 2.0) such as titles.
