Blunts and a guy friend

Hello everyone so I have a very important question I am currently in a relationship of almost 9 months and I have a guy friend who I've been friends with for over a year and me and him are pretty close we hang out all the time not alone but with other people but he asked to smoke a blunt with me later and I was wondering if you guys thought that there was anything wrong with that he's kind of hinted that he could be gay and I don't have any feelings towards him and I am to see him as a friend and I  friendzoned him to many times but do you think it's wrong to hang out with a guy friend smoke a blunt and leave
