Floyd Mayweather proposed to Shantel Jackson back in 2013 with a gorgeous $10 million diamond ring. Apparently, he's taking that back (along with everything else that "legally" belongs to him)!

The couple has officially split-up for good. Since calling off their engagement, the undefeated boxer continues makiing Jackson's life rather difficult:

But that's okay - Jackson is finally ready to move on - if the media will let her.

A rep for the stunning model explains to TMZ Sports:

"Miss Jackson has moved on with her life from Floyd and is saddened that she has had to deal with many problematic and dramatic situations from the media since their break up."

Meanwhile, Jackson continues trying to get her Instagram account up-and-running again after it was "mysteriously" shutdown - "a hit job from someone she knows personally."

Wonder who that might be?

Well, she recently succeeded:

missjackson: "Because I'm Happy..."   

missjackson: "Never fear the enemy that attacks you, but the fake friend who hugs you." 

As for the expensive engagement bling... guess fans will have to wait and see what happens to that!
