Search Results: forget my crush

About a month ago, a guy who I work with but only see on occasion liked me on tinder. I have a huge crush on him but have always been too shy at work to talk to him so I sent him a message. He hasn’t responded, and since he wasn’t making a move at work I decided to start talking to him when I saw him. A few weeks ago we were working together and we started goofing around and teasing each other. I smacked him on the arm in a playful way and a bit later in our conversation he smacked me back on the arm. I was super excited and hoped that meant he liked me. He was on vacation for a week so I didn’t see him again until yesterday. I was in the same room as him and was standing in his way so I accidentally backed up into a table and it made a loud bang noise and he looked and me and chuckled. Then we randomly ran into each other walking down the hallway and made eye contact for a second, and just as I was about to smile and say hi he quickly looked down at the floor and turned around and went back into the room he came out of and told the other people in the room he had forgotten to do something.
I feel like I’m reading too much into this and am just trying to find signs that he likes me cause I really like him.

My friend, who earlier used to like me (but we didn't date or have sex), tell me about his new crushes 😁 I think it's quite normal but my female friend think he does it because he still like me and can't forget 😅
Do you agree with her or think he does it because we are good friends? Also he does it since we met, he flirted girls in front of me
