PLEASE HELP. is my crush playing games or does he not like me at all?

he is quiet and reserved. Has lots of female friends (he is very comfortable and jokes around them a lot). Is geeky.

-we sat next to each other, he initiated a conversation with me, asked my name etc..

-in the hallway he made a really long eye contact and looked me up and down bluntly whilst smiling and said hi.

-there came a period he avoided me until i went up to him and said hi. he again asked what my name was and apologized that he had forgotten it, said he noticed me in the lecture (I did not notice him looking at me at all). he seemed flustered and stumbled upon his words.

-I was talking to a few people and he quickly walked by me and said hi how are you and then ran away without even waiting for a response.

-he hesitated whilst deciding whether to sit next to me or his friend who was right in front of me, but he chose me. He avoided eye contact but When looking into my eyes he stumbled upon his words again.

- I asked him out on a study date (just the two of us), we spent 4 hours together. at first he was uptight and really serious, towards the end he got a bit more comfortable (made jokes, high fived me twice, talked a lot)

-week after that, I missed two of the lectures (I never missed any). After 3 years of not posting anything on facebook, He posted a status saying “missing wifey”. No girl commented under it and the ones who" liked" it were me and a few of his close female and male friends.
