The fighter captioned the post with several statements … including his decision to step away from booze for good.

His plans are:

To “turn this nightmare into the best thing to ever happen in my life” and “get right back on my horse.”

TMZ reports:

Jon Jones allegedly pulled his fiancee’s hair and then headbutted a police car, leaving a dent in the hood and chipping paint, during his Las Vegas arrest early Friday morning, via TMZ Sports.

According to a Vegas Metro PD arrest report, cops were called to Caesars Palace around 5:08 AM for a “domestic disturbance” in a hotel room … involving a white female who was “bleeding from her nose/mouth” and a “black male adult who is a professional MMA fighter.”

When police arrived, they spotted Jon walking near the hotel, where they stopped and detained him.

Cops say 34-year-old Jones became “irate and smashed his head onto the front hood of the LVMPD patrol vehicle,” leaving a medium-sized dent, as well as chips in the paint.

While handcuffed, police say Jones experienced a wide range of emotions. At one point, cops say he threatened to sue the department for handcuffing him on the biggest night of his life.

Jones was eventually charged with misdemeanor domestic battery and felony tampering with a vehicle.

Jon Jones was released Friday evening on $8,000 bail and is due back in court on Oct. 26.
