Added the guy I like on social media and now he looks at me differently?

So I work with this guy and I only occasionally see him when I get floated to work in his department. I also see him for the most part in passing since we currently work different shifts. This unfortunately makes it difficult to talk to him. We’ve interacted a couple of times. I decided to put myself out there the best way I know how at this moment and add him as a friend on Facebook. We do have some mutual friends too so it’s not totally obvious I looked him up. He accepted my request. Ever since I did that I have seen him a couple of times and definitely felt him glaring/ looking at me. I’m worried maybe he thinks I’m creepy for adding him, or if he could be attracted to me or interested now. It’s hard to assume due to limited interactions. I’m definitely at a stand still. Usually when I like someone I try to do something about it since life is short and you never know. I felt that messaging someone I don’t really know would be too forward at this time and maybe I should just let this be for now. Also I may be working the same shift as him this upcoming year and might see him more then. Just wondering if anyone has any advice on my situation. Thanks!
