To Much Tension/ How To Move?

I've been working at this job for a few months and there's this guy I attracted to but so its awkward. I guess I initiated my attraction to him with my stare however I didn't expect him to initiate it back. In the beginning, would hold very intense prolonged eye contact but now we can't even look each other in the eyes. when I notice he was matching me, I started to avoid him because of how nervous. And I guess that whats made him pull away. To the point I always thought it was in my head. But I caught him many times staring at me and watching me. He sat, been in my area, waited for me and would always have his eyes on me before he turns away. He would often have open body language like making himself appear larger and his body pointed towards me. He would sometime avoid eye contact and when we do stare we will hold eyecontact but then he will look down as if nervous. He treats me different from everyone else. He will laugh and openly engage in conversation with other coworkers but with me he doesn't. Its so awkward. When every we pass each other, we will find things to distract ourselves in order to avoid each other or say anything to each other. However, There's been times where we ran into each other, we would apologize (obviously). During those times its like the tension disappeared and everything was calm. I spoke in a gentle tone and he matched me tone. However, outside of that, the awkward tension rises and it's draining. What to do, is it to late or is this all in my head?
