I like my guy cousin should I confess him about it?

As my cousin is 2 year old than me. I had crush on him from a long time and I couldn't know that he also likes me or not so how could I know that he likes me or not. And we had not spent time together. As we both live far away from each other. So how could I know he likes me or not and how could I confess him about my feelings
