I’m creeped out by my new manager?

I met him the other day, and was forced to be with him alone for 30 or so minutes. I was the one making conversation, which he acted like he could care less and only responded with only a few words each time, nothing back to me. I felt like a complete failure after, especially since I have been working for a promotion for so long

It wasn’t until that night (at around 10:30) did I get a follow request on Instagram, from a completely random account that hasn’t posted since 2015. Very basic posts, but as I was looking through likes for mutuals I realized his MAIN account liked them all…which connected the dots of this Instagram account is his stalker account. I asked other coworkers if they got a follow request, nothing.

I feel so disgusted, angry, and creeped out. After making me feel like a complete failure since there was zero engagement in a conversation, he decided to request to follow me on some random account. I have been finding it hard to maintain my professionalism.
Am I overreacting?
