I hate to step on the toes of the Wise-Ass, but…nope. He won’t notice. Assume, when it comes to this stuff, that the male skull is made of brick. He probably thinks you’re only interested in being his friend and, fair warning, he is going to be really surprised you want more. Again, male skull…brick.
You may not want to say it, but it’s either say it or keep pining. He is not going to get the message unless you deliver it to him, in person, and in words of two or fewer syllables. You might try grabbing him by the lapels and shaking for emphasis, or possibly tackling him while naked. But there’s still going to be talking involved at some point.
Sure, you might lose your friend, but it beats pining away for somebody who might not be interested. Lay it out for him, and if it’s not what he wants, move on. Nobody should have “Nobody Knows It But Me” as their theme song, not least because man, Babyface was terrible.
