Can someone help me make sense of this?

Alright so there is a guy who does the following
1. He stares at me. I've caught him a few times and he always makes a weird excuse as to why he was staring at me. Other people have also noticed the staring.
2. Overall body language. He's always nearby when we are in the same room. He smiles a lot when I'm around. When I talk to him, he paces and is very fidgety.
3. He listens to my conversations with other people, and asks me questions about them
4. he's tried to suss out my romantic situation in a not so subtle way.
5. He's a very introverted guy and doesn't go out of his way to talk to other people but goes way out of his way to talk to me.
This leads me to believe that he likes me, HOWEVER; a friend of mine talked to him about his weird behavior today and he denies any romantic feelings. I gave him my number a few days ago and he hasn't texted me at all. So my friend at the end of their conversation told him to text me so I can ask a few questions about this whole thing. He told her he would text me, and he hasn't.
