Girl imitates me and acts odd?

A few years ago I reconnected with a childhood friend. I had noticed that she started to copy my exact, specific hobby and career choice (to impress me I assume), along with imitating my social media posting habits. I never really made a move as I was too focused on my career at the time. A few years have past and recently I noticed something unusual with her online behaviour. For example, I posted a photo of me and a girl-friend coincidentally at the same time she did the same with her boy-friend. The next day, I posted about a specific subject on my story and next day she posts something similar to me (she is not one for posting random stuff online). I found this whole situation abit peculiar even if it was just a coincidence. I ended up removing her on social media platforms because I guess I felt frustrated for some reason... anyway, soon after I deleted her I noticed she had removed her instagram profile photo (something which is unusual as she always had one up prior to this in all the years I had her on social media).

It could be nothing altogether but it just seems unusual to some degree...
