My recent ex and I broke up about ten days ago we were together for a year and 4 months. My friend follows my ex and me on instagram and she pointed out two days after we broke up that he only post when I post. So I tested her statement and I posted on and off for the past week. When I post to my timeline and to my story, so did he. When I only post to my timeline, he did too. When I don’t post, he doesn’t either. It’s weird to me. Why do you think he does that?
