Totally agree with you but just to add - he didn't even post this girl on his feed! Nor was he even tagged in the video/photos. It's just her who is tagged, and he's in the background. He's really not like he's flaunting potentially meeting someone new or anything. She must've been looking for what Anna was tagged in, or her friends did and told her or something. Plus like someone else said - he's literally just there in the background, he's not all over her or anything?
Unlike Niomi who, if I recall an older thread right, was walking around Joe's area hand in hand with another guy weeks after they split clearly hoping Joe would see. But yeah, it's Niomi who is the victim again here...seems more like she can dish it but she can't take it.
