Is he using me? ....?

generally think the guy i sort of like is using me. I get the feeling he likes my friend..but obviously my friend dosent know this and i'm sure another friend of mine is trying to set them two up! Anyway last night i invited these 2 friends and some other people to my house. And the guy obviously found out about this and he text me.(i know this becasue he has been texting my friend and she probably told him she was coming to mine for the night) Anyway, i thought for a while, wow! why is he texting me, he hasnt for a while and in the end he asked whether i wanted to meet him for a bit, before everyone came around etc. He ended up sneakily walking back to mine, whilst we were on the way to mine he said, ohh sorry is it alright if i come to yours? I couldnt say no, as we were basically outside my house. I get the feeling that the only reason why he wanted to meet me is becasue he knew i would be seeing my friend - which is who i think he likes? ............So anyway when my friend said she was going to leave, he quickly said that he had to aswell? Coincidence? I think not lol. he also found out about a BBQ we are having and he has basically invited himself and has also asked if my friend - (who he likes) whether she can come too? If he likes her, then why does he have to try and meet her by using em as the middle person?
