Is he trying to make me jealous? Why do boys try make girls jealous?

Hi, I have crushed on this guy for 2 years. He admitted to me he likes me. Before he went on holiday we kissed each other. 3 months after, he walks up to some girl and hugged her. He looked at me at the same time he was doing this. Why did he do this? Was he purposely trying to make me jealous? Why do boys try to make girls jealous?

It's like we both went to the same college. He followed me into town ages ago to try ask me out. He stood behind my chair before he left college. He went up town on night on a chance to see me. I over head him say to his friend he likes me and I'm really good looking. He told me he likes me. We flirted all the time before he went on holiday. We kissed 3 months ago. Did he try make me jealous by hugging that girl? He looked at me while he was hugging her.
