One thing that struck me about your encounter is how “desperation” sort of worked in your favor. That is, you met someone and the time came to say goodbye…you’ll go your way and she’ll go hers. Unless you do something to continue the contact, it fades to black. People usually put things off, chicken out, whatever, and that wasn’t possible in this case.
Rewinding, instead of saying, “Here’s my email address,” could you have said, “Let’s trade email addresses” as Stranger suggested, so that either of you could contact the other? ‘Let’s see…I can give my info and then climb the walls waiting for a call. Or I can roll the dice that she’ll say no, suggest we trade info…’ If she declined to give you some contact info, that’s a pretty good indication that she wasn’t going to contact you, anyway, so what have you lost?
BTW I think it’s hilarious/tragic that women complain that guys say they’ll call and don’t. Well, I’ve waited for calls that never came so I know women drop this ball as well. Huge sampling error, maybe, but a lot of women like the old-fashioned guy-calls-woman approach. Some of the most liberated women I know have a mental block on this.
To me (and I’m a dumb guy, so grain of salt), we live in such an incredible age—what about IM conversations? You could safely get to know each other, in real time, even use voice. You got the spark, so if you can just fan it, you know?
As for her non-response so far: as Tom Petty sang, “The waiting is the hardest part.” Murphy’s Law being what it is, who knows? Maybe she had to rush one of the kids to the ER or is dealing with a broken down car or…or… It’s very important to be patient, not appear desperate or stalkerish. I say give her a little more time. The weekend approaches and that may be when she gets a chance to catch her breath.
Re: googlefu. I think it’s okay to know it, do the research, etc. I don’t think you should mention it to her or use it to contact her until/unless you’re ready to throw a Hail Mary. It could backfire too easily, make her feel creeped out; OTOH if you have no other way of contacting her and decide to give it one last chance, be UBER casual… “Hey, I was in Facebook tonight and…” (followed by plausible way you stumbled across her). E.g. if you happened to have a common cyberfriend, that would be gold. Or, surf the net for golf sites till you find her in one. It can’t appear to her that you were cyberstalking.
@Trouble, @Harriet—I’d be very wary of calling anybody at work. Some people get in trouble ("No personal calls!) for it. And work=food on the table, so some feel pretty threatened by it. I don’t call people (even friends etc.) at work unless they first give me a green light. Sometimes the green light is provisional: “Don’t call before 11:00” etc.
ETA: On second thought, “researching” her on the net is actually a good idea, and I think it’s good for both sexes. Suppose you found out she’s married, for instance.
