Confess To Your Crush

EXPERIENCE:

There is one time I wished I did confess to this guy I liked in my freshman year. I didn't because I knew he had a girlfriend although he wanted to break up with her (he couldn't because she would threaten to cut herself, he tried telling her parents but stuff just didn't work out).
I think he liked me (maybe I deluded myself into thinking that though lol) whenever I would talk to my other guy friends he would walk up, stand behind me and hit me on the head with a book he was holding (not hard or anything just playfully so that I would look at him) then he would say "Hey you're in the way" when I was not and he could have just went around. Another time he grabbed my hand and drew on it saying "you're in my club now" but when my nosy friend asked what he meant he got all weirded out and was like "it means nothing" so he started drawing on everyone's hand so it didn't seem like anything.
We had this weird game in class that we would hit each other on the bottom of each others backpack so it seemed like we were hitting each other on the butt and be like "Mmm fat backpack" whenever my friend would hit his he would go after me. ALL THE TIME
One last example: I was joking with a guy friend of mine and I was taking his picture. We were laughing and messing around. Well after when I was scrolling through my camera roll my friend pointed out that the guy I liked got in the picture. When I zoomed in he was looking directly at me-the camera- with a look that was like "excuse why are you taking random photos of him" My friend said he looked jealous.
Unfortunately though I never did get to find out if he liked me and I never got to confess. He got into a fight in the middle of class on a Friday. The weekend passed and when it was Monday everyone was talking about how he up and moved to Iowa over the weekend.

How about you guys? Ever regret not confessing to someone?
