How does my friend feel about me?

Alright,so I have this guyfriend,Tommy,and in a way,I like him.We became good friends last year,but when I admited my feelings to him at one point last year,he said he didn’t care if I liked him,and that he didn’t have the same feelings for me.So,in the beginning of this year,Tommy said that he had “sexual” feelings for me,if you know what I mean,but I didn’t know how to really react.I go to school the next day,and I wanted to see if he liked me,so I told him to kiss me,and he did.Him and I then made out on his locker. I go home that afternoon and he said that he did like me,for about 10 minutes,and minutes later,he said that he used me for sex.We both forgot about that moment,or at least it seemed,but every now and then,it comes back to me as if it happened yesterday. For a while,it seemed like he liked me,in school,you know,by smiling and just,completely staring at me,and I don’t know why.Incase,you’re wondering,we don’t talk in school,but only over the computer. On the other hand,I still like him and all,but since he did find out that this girl,who is also my friend,doesn’t like him anymore,he starts to come around,and tell me that he’s horny and so forth.I don’t know what to do.I do like him,but I absoluetely refuse to talk to him about that ‘cause everytime I tell him my true feelings,he just seems to blow me off and say that he doesn’t care.Please help.
