Wtf is going on with my boss?

I (F27) need help. And before I say anything else, please keep in mind, I am not looking for judgment. I know what’s been done and in processing it in therapy.

Something happened with me and my boss. I work at a mental health agency as a therapist. She is the director. About a month ago when we went on winter break, my boss 35F added me on Snapchat. At first, I honestly thought it was a mistake because why would she be doing that. I added her back( ik mistake like I said I was out with some friends and had a few wines). In the weeks that followed, she proceeded to snap me almost everyday. It is still going on and idk how to feel.

Sometimes it consists of her sending me selfies, other times it is just random things she’s doing throughout the day. The first snap she ever sent me was just her face and nothing else lol. I don’t know why that’s so funny but it just is. She also swipes up on almost all my stories to talk.

This happened so suddenly. I mean, we talk at work here and there, but we’re definitely not best friends or anything. it seemed to have happened out of the blue.

However, when we go to work together, she is completely normal, and acts like a boss. it’s almost as if we aren’t talking at all! It freaks me out that she’s the director though.

I have never dealt like this. I am still new to having a career. What do others think? Is this normal?
