Questions: Guy's Behavior

Actually I feel a bit strange to my older cousin's attitudes on me since 1 years ago.

He's attitude was like :

1. There is anonymous number represent from philipine calls me in the mid of the night without giving any responds. Just silent. And suddenly ended up the call. I thought this number refers to my older cousins, because I just knew that he just already move abroad to philipines at the same times while this number calls me. And this number is such a new phone number...

Perhaps he knew my number from my little cousin that I give her my phone number. Because in this case I never give my number phone to him before. I alredy analyze and check this number phone identity but its seems like he try to hide the identity.

2. Next day after that calls, He make a instagram story with caption that he is in the condition that he has a girlfriend but at the same time he likes someone else.

3. He secretly looks at me from the distance but not too brave to looks at me directly in front of my eyes.

4. He give me some money through my sister. while he was sitting next to me. Why would he doesn't just give that money directly on me? Why while I say thank you on him he just looks awkward and doesn't brave enough to looks on me?

P. S. :He's not typically such an introvert or shy person.

Is that a sign that he has crush on me? I want to ask him about this, but I'm quite afraid about the consequences.
