Search Results: signs that a shy guy likes you

So, I have a crush on a guy that is in one of my classes in college. He is a grade older than me and tends to be the "joker" of the class. He will constantly try to make the professor laugh with "stupid" answers and in total make the whole class laugh. He isn't stupid or anything, he just likes that type of attention. So, I started "liking" him when we had to be put into groups for an essay peer review. It wasn't just me and him though, it was me, a girl, him, and another guy. So, the entire time he barely talked to me, and just talked (flirted) with the girl and the guy. He was basically ignoring me for no reason even though I barely knew him and never even talked to him. While he was talking with the girl (who sits next to me), he seemed nervous (he was fidgety and looked uncomfortable). My first thought was that he was nervous around the girl he was talking to, but if he was nervous around her, why would ignore me completely? I thought he was attractive before this incident but this situation made me a little confused.
So other than that incident, he never really seemed SUPER into me or was showing me all the signs. There have been a couple of times where we locked eyes with each other for a few seconds. When we do look at each other, he never looks away nervously (like a shy guy). He often keeps the eye contact. In class he does sit diagonally from me so, he often tries to position himself closer to me. He barely talks to me in class (ignores me) and he sometimes just asks the girl next to me random questions like "what was the homework?" or "did he grade that test?" There have been times where I could see him glance at me while looking in my direction. Outside of class, I barely see him or talk to him (bad sign probably lol). He does this weird thing where the minute that the professor says bye to us, he runs out the door.

I went home with a coworker (professional organisation forward thinking (London so huge office) but they are fine with office relations).

We were both a bit shy at work the next week, but kept it professional and chatted friendly to one another.

The next week he would stop by my desk to talk more often than before. (extending trivial conversations).

We ended up hooking up again 2 weekends later [this time only a kiss, and then we went to dinner after - we stayed chatting till it closed].

The next night we were out again and went home together and hung out the day after.

I am yet to receive any communication outside of the office which I think is odd (i. e. social media). He did mention he doesn't have my phone number and I missed an opportunity to give it now that I think back.

When we are together he asks loads of questions about my interests , he talks about his past/future, and there was a bit of "next time" talk. He also asked me some more personal details - when I questioned why he said he wanted to build a connection. He also said I was a bit hard to read - (def. true). He said he likes me on more than one occasion. Lots LOTS of cuddles initiated by him. He is quite caring and not selfish in bed.

He calls me nicknames and his work friends are acting more friendly to me, we also have some inside jokes which have come out in passing a few times.

Do you think he is interested - all signs point to exploring more and that he has feelings, but the lack of communication I think is really weird and I find confusing - I raised this with him (he said he doesn't like chatting on social media).
