There’s a guy in my college. Though he is from department we have never been in the same class. So I haven’t talked to him. He just looks directly at my eyes whenever I see him somewhere. He is good looking, a lot of girls in my college like him. I was not interested in him at first and I’m not looking for a relationship as of now. But lately whenever I bump into him, I feel like my chest tightens but it’s just for like 2 or 3 seconds. Why do I feel like that? Does it mean I like him? Kindly help me because I have never had a crush before and don’t know what it feels like.also is he interested in me?if so why hasn't talked to me yet?
