A few months ago, he mentioned he likes me as a friend...now he is acting different. Did his feelings change??

So I met a guy 2yrs ago, and we have become really good friends. 1yr ago, I started liking him, a LOT. I think he may have caught on, but we both kept it platonic, since he had a gf he loved. We just studied & talked a LOT. 2months ago, the gf broke up with him. Well, my friend (against my choice) asked him the day after if he liked me, and he puased a while & said as a friend. I wasn't mad, & we talked tons (4+hrs) almost every other night online for a month. Grew SO close. I go back to school and he is blushing around me, staring nonstop, and I get home and he texts me TONS, and even called me once to talk. So, I text him back some, and call him too. But last 2 weeks at school, it is only staring & awkwardness. Last night I IMed him and he seemed occupied, so I let him go. Then he texts me later on. Once, he even went off about how "girls should be straightforward". Does he LIKE like me or no? Or does he like me cause I like him? Is what he is doing considered just friendly???
