Crush crushing me.

I know this guy likes me, but he's too introverted to start a conversation. Do guys like it when a girl initiates a conversation? Also, we don’t see each other anymore since he’s doing his master’s in the UK. Do you think he might find someone else there?

P.S we both have a feeling ke we like eachother. Ab kya karun? Should I message him or just let it go? He is my crush for like 3 years now. Did bachelors in the same university.
