Replying to Drunk question

alright so my friend came over tonight and we went to the bars. he got mad drunk and was trying to hook up with this ugly chick and i kept telling him not to. well its like 4 and he was planning on sleeping on my futon. he calls me up and hes like yea ima bring that girl back to your place. im like uh no dont, i dont want you two screwing on my couch. so he says alright then give me my keys and ill drive her back to my place... im like your hammered thats not a good idea. so he came and got his keys. am i an asshole? i dont want people screwing on my couch but i dont want drunk people driving. am i in the wrong? i think i am.
