So there's this guy at college that I have a crush on. I'm almost certain he likes me, since he's always really happy to talk to me, his friends tease him around me, and even today when I was heading to class, he made the excuse to go early to class (so he could walk with me), and his friends laughed at his excuse. He also gets a little shy around me at times as well, as he noticeably gets nervous about initiating any conversation with me. I mustered up my courage today and asked him out on a date. He hesitated for a few moments and then said yes. I then told him he could say no if he wanted to, but he said: "No no no, it's okay. I like talking with you." and then suggested to go out for lunch together the next day. Why did he hesitate? Is he just shy? Because I'm pretty sure he's interested.
