So far, Ronnie's girlfriend?/baby mama Jen, who has really been a main talking point on the show as far as Ronnie goes on Jersey Shore: Family Reunion (and the cause of him being super emo this season) has been arrested twice for assault and battery toward Ronnie.
The latest incident was Jen beating Ronnie in a car (hours after they were at a party together, since Ronnie is trying to keep the peace out of fear Jen will try and take full custody of their daughter). Their daughter was apparently in the car, too, when Jen was beating on Ronnie, and friends are worried that she could accidentally get in the middle of future assaults.
I feel bad for Ronnie, man. You can tell he has some demons he's battling, but you can tell he's trying to do the right thing, too, especially when it comes to being a good father. Here's hoping the situation gets handled peacefully and no one else gets hurt. (Because I really miss the Ronnie laugh and am over seeing the Ronnie cry nonstop.)
