Is he really interested?? or nottt =/?

This guy in my cl sometimes when i don't look at him, he looks at me but me and him don't exactly talk to each other but during half term my mate told me to ask him to come out with us... my mate and that guy is close friends so yeah.. on face book i asked him and he was been all kind on me and said that he would inbox me in the next day so the next day i waited and waited and he didn't so i had 30 minutes to go and meet my mate so my mate told me to send him my number and tell him to text me if he is coming or not but unfortunately he didn't get the inbox message that i sent him till night time and i was get to him on face book chat thanks for not letting me and that and he was get saying sorry and he fell asleep while he was about to inbox me we spoke till 12:45 or something at night and he texted me while he was still chatting to me over facebook saying ' hey its luke just facebooking it up lol ' something like that and i was wondering why he did that??? and his most of the time his online and he wont chat to me unless i talk to him :( whats that all about?? and once i started a convo with him on facebook and then he quickly entered and was like ello ello.. and asked me if i had msn and i was get yes and he added me from there and we spoke on msn and he suddenly brought his favourite band and he went on cam and showed me his room and i didnt ask him to and he was on cam to me whole night.. does this mean something
