confused about a taurus friend!!!!plz help

i am a leo and lately i've had a taurean friend whom i have known a year before..but actually we got close just a few months ago..we started by telling each oyher about our lovers whom i and him had at that time.he was so interested to know about the one i was in love with.i refused to tell him at first.i was too shy but then i did.he made me trust him so soon.i asked him about his girl too and he asked me if i would be his faithfull friend.i nodded: sure,i am!...life went on.i broke with my lover who was so mean to me.my taurus friend knew about everything and listened to me so understandingly.i was so relieved and calm when i chatted with him.he also asked about my ex-fiancee -or as he was about to be- and why it didnt work out.that just made him know a lot about my personality,how i felt about people and life,and what i needed to have in my life..i guess he figured that qiute well!....about him,he has a girlfriend of the scorpio sign..he told me about her and i used to give him tips about the presents he should bring her and so on..everytime he came back and told me happily how my tips worked..then he started to tell me how she became moody and made him feel unstable in their relatioship.he gave me more attention and laughs and told me about his personality..how he is proud and direct and frank person that people think he wasnt serious just because he is saying the bare truth....one day..he came and told me "i broke up with her after a fight we had last night i know she will want to return back to me but i wont..my pride is so much hurt..it is over"..i was sorry for him and showed my compassion..i hid my happiness that he became at last free!!!!we talked almost everyday and i think we looked for each other.i dont want to give it more than its actual size but i believe he liked me.i knew we had a spark together and we thought we were so attractive and passionate about the same things..that day he was so attached to me that he didnt want me to leave as if he wanted to tell me something but i had to go home with my dad.he asked if i would come the next day...i was so happy.then a day or two passed and he told me he was back to his girl and he asked again about my advice what he should do.i was really sad that day coz my parents were having a divorce.i told him everything i have inside..and i know how dramatic leos are:S he was suppotive and told me he was beside me and asked me to lean on him with my emotions but not too much!!!!

does he consider me his sister—?!!! i didnt want to push him so i hinted that i would be glad if we were friends forever and that he was a great support to me.
