Search Results: ignoring each other in public

This guy and I work together.
Everyone at work thought we had a crush on each other. There were times where he would approach my desk. He even laid his body across my desk to look at my pictures. He pointed to one of my pictures and gave it a thumbs up and said cute. He told me I was socially awkward. He sometimes messes around with me by pulling small pranks. I remember I confronted him about the rumors of us and asked if felt awkward because everyone kept pushing us to get together and I didn't want to upset him with what's circulating. He would get really irritated when people made subtle comments about us. He said didn't feel awkward and didn't deny anything. He joked that we should go on a double date. Another day he told me to take his number down if I want to talk about it more. I didn't take his number but got his social media page.
He started to act weird and ignore me and even talk about me to coworkers. I got upset and he/I didn't talk or interact with each other for a week. I deleted him off social media where he can't follow me or see my post. Then I find out he's seeing another person who used to work with us. She's supposedly engaged to someone else but they've gone on dates. She sent him a romantic gift to our job. So I ended up backing off completely. Fast forward to now, I saw him snooping on my social media page watching my stories. (My profile is public).
We slowly started interacting by making small talk again. He messaged me and asked me to do a favor. I don't know why but I said sure. He wanted me to make something for him. I ended up giving him my number. I did the project for him and he says thank you, he appreciates it. Didn't even say thank you, I owe you one or I'll give you some snacks... Nothing. I don't know if this guy like legit hates me/likes messing around with me for fun.
