New to this

I started a new job in April and met this guy, we went to high school together but didn’t know each other well. In the beginning we didn’t get along well but I have started to become more and more attracted to him. We text for work regularly but yesterday I texted him and told him I had been fantasizing about being with him, about the things we could do together. He has not responded to the text.

I don’t feel like I did something wrong but I’m worried about seeing him at work now.
