I used to thought women are the most complex kind in this earth and there come my crush. He always send mixed signals to me and now I don't know if he interested in me or not.

Background:

We're both 18

He's a brilliant computer scientist (like superb!)

He doesn't talk much and often isolates (but still enjoying) himself our class

We rarely meet (once a week or less) so we only communicate online

He's quite feminine and fragile (but I still think he's manly, subjectively)

We both play CSgo but we have never play it together...

Positive signals:

We once have a sleep-over at my class and I got so drunk so I ended up holding his hand and fall asleep and he didn't take his hand back (and my classmate said he was kinda enjoyed it)

Although we didn't talk much but when I ask if we can use his kitchen to try this cake receipt and he doesn't say no. (he allow a girl come to his house even though she's not that close to him)

When I came to his house, we have a nap together again (just the two of us), we were lying next together so close that our hair was tangled and I can feel his subtle scent and his breath and rather than being uncomfortable, he fall asleep deeply

He ask to teach me how to code and was kinda enthusiastic about it

Negative signals:

He often "seen" me on messenger

He showed reluctance when I asked him to teach me coding (more deeply and academically)

He doesn't have any signs of "what guys would do when he like a girl" like initiates a conversation or talk to me much, or ask me out or any trivial details like pointing feet at me or like to draw near me,...
