Nope. If you know he’s not interested, you’re just putting him in an unnecessary awkward position to have to tell you that he’s not interested.
Which is something you already know. So it puts you back to square one except now you will odd convos and uncomfortable face-to-faces with your closest guy friend. You might actually slightly mess up the relationship.
If you thought that there was some chance of him being interested in you, then of course. Go for it. Closed mouths don’t get fed. But that doesn’t sound like your situation, so there’s no good reason to create that conversation.
But since I believe in love and happiness, and all that Al Green stuff, perhaps you can allude to it without saying it. Be extra flirty and girly and see if he responds to it in anyway. Since you all are close, he won’t just look at you as some chick who’s flirting that he can get in the sack easily. In fact, he might break some sort of manlaw and talk to you about it to make sure that you are both on the same page, where you can exert some plausible deniability and say you were just flirting because he’s so much fun, etc. Or you can just blame it on the al-al-al-al-alcohol. It works every time. Patron you my homey.
So yes, be easy. Enjoy your friend. Maybe something will blossom. But if you know right now that he’s just not that into you (lol), then there’s no reason to force an issue where you know the end result.
