Well the story said she removed all pics of them together on her social media, and she hasn't, so at least that part of the story is false. I'm sure players do stuff on the side, but JD would be a fool to lower his standards. If he's grabbing chicks on the road way hotter than the one he's dating, then understandable, but being horny should have limits.
As far as Jackie, I think she's attractive. You guys are being rough here. Does she look like the girl at the bar who goes back to your place after one drink? Yes, but maybe that's part of her appeal. Just wrap it up.
