Boxing star Gervonta Davis is finally admitting he was "wrong" for getting violent with his ex-GF back in February ... and claims he's since sought professional help.
As we previously reported ... the 25-year-old WBA lightweight champ was caught on camera aggressively grabbing his ex, whom he has a child with, at a celeb basketball game in Miami on Feb. 1.
Footage of the altercation was disturbing ... it showed the boxing superstar clearly putting his hands near the woman's neck and violently grabbing her away from her courtside seat.
In other angles of the incident, obtained by TMZ Sports, the footage appeared to show Davis later attempting to throw a punch at the woman when the two got inside the locker room area.
