I am in school currently and have a crush on a guy who I sit with at class. I can't figure out if he likes me or not. He always starts the conversations we have, but all we ever talk about is the class we have together. He sometimes has his body turned towards me when we talk, and when we do talk he maintains eye contact the whole entire time. In addition, when we do not sit by one another I notice him glancing over at me and sitting in a way so that he can still see me. I don't know if this is important, but he also always plays with his hair. I am overreacting? I'm just confused by the mixed signals.
