You can do a lot in one year with a porn star ... and Charlie Sheen ... enough so that the engagement is now off.
Charlie tells TMZ ... "Scotty and I had a great year together as we traveled the world and crossed a lot of things off our bucket list."
Sheen says it's more important right now for him to focus on his 5 kids ... and, we're guessing, keeping the peace with his exes.
TMZ broke the story ... Charlie got engaged to the ex-porn star last Valentine's Day in Hawaii ... Sheen called it true love.
But love stories don't always end with white picket fences. The good news -- no child support, no spousal support and he doesn't have to buy her a house.
