^^ I wouldn't say you blew it. If he's still reeling from a bad breakup, then either:
a) he probably wasn't ready to call you, and wouldn't have regardless of anything you did/said; or
b) he probably wasn't ready to call you, and if he did he wouldn't have been ready to date you and it would've been a mistake to date him.
Do you want to go out with someone who is still feeling hurt from a (recent?) breakup? Because you don't need someone who still mopes for their ex.
I know unrequited crushes are painful, but I feel that you're better off.
I remember back when I was in university, living in dorms on a floor with a lot of really good-looking women around, and being rejected quite severely (I overheard a group of girls saying something like "That <my>, he's so weird, eh? What the hell?"). I was hurt, but then after some long walks and a lot of self-reflection, I learned a lot about myself, and realized that it's better to be single then to waste my time pursuing people who thought badly of me. So I stopped trying so hard at winning the affections of women who didn't deserve my attention. It was a gradual process, and one that involved different types of rejection (by people who were genuinely friendly, but only saw me as a friend), until I found the woman I would marry.
At the end of the month, we'll be celebrating 3 years married. Good times
It was the year of fire… the year of destruction… the year we took back what was ours.
It was the year of rebirth… the year of great sadness… the year of pain… and the year of joy.
It was a new age. It was the end of history. It was the year everything changed.
The year is 2261.
The place: Babylon 5.
