Search Results: feelings for the person you once loved

I have a crush on this guy at my school. We have similar interests in art and music, and I love his sense of humor and friendliness. We're both in a few small clubs together at our school and we are pretty good friends and on good speaking terms. Since the beginning to about a month ago, I always initiated conversations with him and we never really talked except for some casual conversation during the club meets, but in this past few week a lot of things escalated. Because I really wanted to do something, I tried to smile at him more and talk to him in the past month. In this week, he sometimes came up to me during lunch, and messages me in the evening, and we started talking every day, just about anything, and sending each other videos and pictures of things that would make the other laugh. I told him that I got my first guitar for my birthday and he got really excited about it because he LOVES guitar. During that same week, we hugged once on my birthday and sometimes he talks to me when we see each other. I feel (and hope) that he may like me back, which would be amazing, but I'm skeptical because he talks a lot about guitar with me and a few times asked me about my guitar... I'm not sure if the increase in interactions between us is because he really likes me, or if he is just hoping for another person to talk with about a shared interest? Maybe because he loves guitar so much and he's a friendly and nice person in general, that he could just be talking to me because of that?
Now that history is over, question: do you think this guy may really be into me, or if he's just excited about guitars maybe and the fact that I'm learning to play? Should I approach him about his feelings or not and how?
Guys, what reasons could you have for talking to a girl? What will you try to talk about?
I've never been in a relationship in my life, so all your responses are very appreciated!! Thanks so much!
