The article about "how to know if someone loves you" lists several reasons why the guy might not "admit it", but leaves off what's probably the most common one -- he hasn't figured it out yet. That cliché about it being obvious to everyone except the guy himself? Very likely. Especially if he's on the geeky side -- aspergers and alexithymia go hand in hand. And apparently "male alexithymia" is a real thing all by itself -- one of my former shrinks did a thesis on it!

I like this one a lot.
