Guys, How should tell my coworker that I like him? Guys can you help me?

Some people think he has a crush but sometimes I’m not sure. Yes I do like him.

Here are some signs that makes me and few others think that he likes me:

-Always teases me a lot/eggs me on to do better at work

-Always says my name first or uses me as an example in our work group meeting

-Always volunteers me for a new project whether jokingly or seriously

-Always gives me advice even when I don’t ask for it

-Always tries to help me but sometimes forgets his promises to help me too (kind of contradicting I know)

-Brings up our past somehow sometimes (We met in college actually cuz we had one class together but then changed to different majors later on. Always saw each other on campus and talked to each other tho. Ironically he gave me advice when I was going through issues with my boyfriend during those college years and he kinda knew my ex too from mutual classmates/friends.)

-He comforted me at work one time when I was crying. He refused to leave unless I told him what was bothering me that day.

-Always wants to show off his new project at work to me

Just a little update

Just yesterday I kinda smacked his shoulder when he was teasing me but he didn’t seem to shudder at that. He just laughed. Also I kinda suck at flirting so any tips on how to flirt would be great lol.
