Adrien Broner -- Begs Fiancee to Take Him Back ... 'Baby, I Miss You'

Adrien Broner is in crisis mode -- BEGGING his fiancee to take him back after reportedly cheating on her.

The boxer and his fiancee -- aka Miss Louiebags -- just had a baby together earlier this year ... but she hit the road after Broner's reported trickiness.

Clearly, the split is driving him crazy ... and he's making all sorts of videos begging her for another chance.

"Baby, I miss you. I hope you see this. Call me, I'm hurting."

Broner says he's been so distracted, he recently got pulled over by the cops because he couldn't think straight.
