boys :/

i've had this guy friend for ages (he has a girlfriend) and we are pretty close, but last night we were talking and he commented on how much he's likes my ass. now don't get me wrong that made me feel pretty good, but he kept talking about it and then he was pleading for pictures. i told him no and then i went off at him because i'm also really close with his girlfriend, but now he's not talking to me and it makes me feel as thought i have done something wrong. even though it's his fault, i don't want to ruin our friendship. i don't know what to do 😒
