I was stalking my ex-gf when I realized nobody has seen her alive in a year BUT she keeps posting

Will knew he shouldn’t have been stalking his ex-gf’s Instagram but he couldn’t help it. He had just gotten out of the psych ward and there she was living an influencer life with her new perfect boyfriend. He just wanted to see if she ever thought about him like he did her… But as Will was analyzing all her photos he realized that they were all old pictures she had re-edited to look new. They were old photos. Why would she only post old photos? Photos that he had already seen, some he himself had taken. That didn’t make sense. The more Will investigated the more he realized nobody has actually seen his ex-gf alive for over a year and none of the pictures had been taken in the past year… so who the hell was posting the pictures?
