Since you write that you know you’re being overly sensitive and jumpy, the solution is to stop doing that! It’s that easy. 🙂
The problem is really yours since she hasn’t done anything wrong in the two weeks you’ve been dating. You’re focusing way too much energy on controlling the relationship. The tricky part of any relationship is that there are two people in them! 😮 And you only get to control of those two: YOU!
So, while it’s fine to hope that things work out, the reality is that you have to let things take their course. Your girlfriend is within her appropriate bounds not to call you. You’re the guy, you do the calling. Sorry, but I agree with her on that one and your “personal line in the sand” about her calling is not mature, and is going to get you no where fast with women who adhere to my philosophies of dating. So ease up on that line in the sand. 🙂
When you write that things have been so good between the two of you it’s “like something out of a storybook” I’d advise you to quit reading those storybooks! I mean, they’re fine for kids, but adult relationships take all sorts of twists and turns and you have to be more of a dancer to adjust to your partner’s moves, and vice verse, to make a relationship work, so maybe instead of those storybooks, you can start watching Dancing With The Stars instead! 😆
I hope this helps. Good luck — and let me know how things go.
