If I was smart back then, I won't be married to him.
The only thing I'd do differently is have the hospital remove the gallstones without removing the gallbladder, have hubby get blood work to find out he had HeP C five years before it hit hard, and insist his doctors check his arteries to his heart in February 2015.
Everything else? Yeah, I could have made smarter decisions but then I would have never met him.
