Does he like me?

well ii known this guy for awhile and im not quiet sure if he likes me or not . about a week ago I told him myself that I like him . as a reply he said that he knows. but he didnt say anything about liking me or not liking me . we talk on the phone and on aim like eveyday . most the time he will be the one IMing me or calling my phone late at night. he basically tells me about everything and he always tells me how he goes to party and how all these girls are all over him. once when he told me I replied to him saying “and I care why ?” and he was like lol just telling you what I remember . is he trying to make me jealous ? at school when I see him he would look at me and smile and either wave or say hi to me . once I made him a cupcake and I told him to go to school early because usually he doesnt and that day he actually did come early and he brought me breakfast. he walked me home well halfway once and has invited me to places quite a few times. there is also this one time when out of no where he was like I feel lonely and I was like what do you mean and he was like seeing all these couples you know. and ii was like oh well are you inerested in anyone and he was like “ absolutley not xD” with a smiley face . do you think he is interested?
