My friend sometimes makes me think he likes me as more. He always seems happy to see me, and makes lots of eye contact. He tends to joke around with me a lot, and will generally look at me when we're in a group. He often asks my advice and confides in me about things. He tells me things he says he hasn't told anyone else. He regularly offers me lifts home when there are other people with cars too, and sometimes I feel like he's standing closer to me than other people do, or than he would with other people. Does he like me or are we just good friends? How can I tell (without asking him)?
