Search Results: how can i let him know

So I have this coworker he a very quiet kinda timid man we will call Zack. I'm considered a Zack expert at work because again Zack doesn't really talk much but I talk constantly so I tend to get him to speak to me. Zack will come find me to let me know it's break time and has say with me during lunch once or twice to talk to me about books.

He tends to startle me because he's a rather small man and quite so I never know he's there and he always appears close by me like if I lift my elbow id probably bump him.

He tries to help me when he can and I don't know if he does it because he himself doesn't like it or because he knows I have damage to my ears but he sets pallets down quietly instead of slamming them like everyone else.

He will also try to pull stickers and stuff that get stuck in my hair off me.

He even picks on me a little bit like might make fun of my spelling

I tried to invite him to see a movie by saying I was going to see if you liked xyz movie because if you did I was going to invite you to come with.

he didn't say no but he also didn't say yes he kinda just evaded the question but asked if I ever went and seen the movie like I wanted.

He's kinda hard to read

Is he just being nice and tolerant of me as a coworker dose he want to be my friend or is he interested in me I just don't know?

I briefly dated a guy (about a month). He let me know he didn't feel the spark he was looking for. He said he loved spending time together and would love to be friends. I can see how we are not a good fit based on a couple of red flags I saw. I would like to ask him to casually sleep together. Any advice? And have you ever turned down a friends with benefits situation and why?
