i don't think he's interested ?

okayy, so my friend's bf wants to hook me up with one of his friends... loll he's really cutee, and he's seen pictures of me and thinks the same. So we started texting and he was being all nice ( I haven't met him ) but then when we hung out with my friend and her bf it was kinda awkward, I dunno if it's cuz he was with his friend, he's was acting like what he'd do when he's with his friends... When I texted him he was talking to me but this time with less smiley faces, does that mean anything?! Although I asked him if he wanted to hang out again and he said yees. So helppp? I don't get it !!

Thank you :)
