Intense talking of serious subjects, no flirting whatsoever, no 'dates' (get togethers at places), yes, you are clearly delusional if you think this guy is getting in her pants. Sorry, the laws of attraction just work differently, it's not my fault, if you believe otherwise, then you're the fool.
Like p2dr said, he's now in the friendzone, and there's no way he's getting out.
...And yes, wtf do you expect after no sensual action of any kind after 3 weeks, that they're going to fuck happily ever after? Guess again.
