The 36-year-old quit her role on Suits (and gave up acting altogether), moved from Canada to London, shut down her lifestyle website, and had to leave one of her rescue puppies back in Toronto.
But it appears she's not the only one in the relationship prepared to make sacrifices: Prince Harry has given up smoking for his non-smoking fiance.
"Harry has promised no smoking at all at home," the source told the Daily Mail. "It's not nice for Meghan as a non-smoker. So there's no more hanging out of the window for a quick puff. Harry has quit for Meghan."
Admittedly, giving up smoking isn't anywhere near on par with everything - including hostage training - Meghan has to do for her new royal role, but it's a start.
