Hi Guys,
I'm of the school of thought that says, get her number first and then give her yours later, after she's proven that she's not mental and is worthy of your attention.
This accomplishes a few things:
a) By taking the initiative and getting her number without giving her yours, you've told her that you're going to be moving things along. In other words, you're the one that's going to be leading.
b) If things go well, she'll either ask for your number at some point or realize that you'll give it to her AFTER she's cleared that first validation stage. In other words, she has to prove that she's worth giving your phone no. to, because you're the prize.
c) If she wants to be with you, she has to be flexible in her schedule and be or become available when you call and setup a meeting or a date. Your time is valuable and she has to compete for it against all the other things in your life.
d) You don't give up your power. You let her into your circle slowly, as YOU decide.
If giving out your phone no. first or right away works for you then run with it. However, if you haven't tried it the other way give it a shot and see how it turns out.
Just my 2 cents.
Cheers,
Mav
