I would really appreciate someones advice?
I met this guy just before Christmas when we were put together to do some group work in college. I only worked with him for like an hour but I really liked him. Before we were put into groups me and my friend had been looking at him (he was wearing a hat with reindeers on, she was wearing a dress with reindeers on it...it was all a bit awkward) and I think that he followed us to work in our group! (I noticed that when I would talk I would see him similing and when one of the other guys said that I should read out loud because I have a nice voice he agreed and smiled...he was probably just being friendly though)
Anyway that was the last I seen of him because he is on a different course to me, but the odd time I might see him around college. (I found his fb and twitter...like a creep and he just seems lovely and like perfect for me because we like the same things and have the same views on things)
So I noticed the other week that this guy is in one of my classes and I think every week I have noticed him and his friend looking at me. I also seen him quite a bit in the hallway this week and I think he was looking at me then too.
But then I saw on his twitter that a really pretty girl on his twitter posted a picture of him and was all like ‘Smiling with your teeth. Shocked!’ and he wrote back ‘Anything for you.xxx’ I also seen his friend left a comment teasing him about her and then he posted about listening to Take Care by Drake and looking at the stars and he also changed the line under his name to the lyrics of Wonderwall '...maybe, you're gonna be the one that saves me' so he is definitely thinking about someone which is probably her. Now I feel all sad and don’t know what to do From what I see this girl is not short of male attention. She is 3 years younger than this guy though and I am only a year younger than him. Should I just try to move on and forget about him? (Sorry this is so long)
Thank you if anyone answers!

well if you like him and you don't know for sure that he likes this girl, right?..then don't just move on cause maybe something could happen. i mean, he could be talking about you. you should try talking to him, if not in person, then on Facebook or something
