Ex-‘Teen Mom’ star Jenelle Evans appears to be leaving her volatile husband, David Eason, for good — this after the guy allegedly pistol-whipped a man and got arrested.

We confirmed Eason was busted and booked Friday night out in Columbus County, North Carolina on two different charges — assault with a deadly weapon and communicating threats.

As for what happened leading up to this … reports say, and Jenelle seems to confirm on social media, that a scuffle broke out between a couple of her guy friends and David … when she returned to the house to get some of her things. Eason allegedly pistol-whipped one of the dudes over a misunderstanding over keys.

Jenelle is reportedly staying with a relative now.

She wrote on FB, “I just want to let the public, tabloids, and my fans know that IM OK, IM SAFE AND SO ARE THE KIDS! I’m going to take a few days out to myself to gather my thoughts and focus on what’s going on so I won’t be on social media much. I love you all for the support that you all have shown me and I’ll be stronger and better than ever soon!”

Jenelle also told Celebernation that it was time she and David went their separate ways … again.

Cops released Eason on an unsecured bond.
