Is she playing games for attention?

Have this woman who I use to work with where we got stationed to different locations. I’m in San Diego she now stays in Maryland. Before I suggested we go out on a date and see what happens. Got shot down being told she seeing another guy currently at that time. I say cool leave it alone not really putting self back to try again after getting turned down. Still friends on Instagram so we see each other stories and photos that get posted. Out of nowhere she goes and block me on all social media without warning confused as to why but look at it so be it. The day after she goes and unblock me on Instagram just to like all the photos I recently posted and doing having fun. Thought it would be better to at least respond with a simple how things going just to see what happens. Within minutes of me sending the message instant reply and other social media outlets with me available is unblocked. Wanting other opinions on what the play she going for doing this.
