She's a good plate, she'll be staying, I'm looking into making things easy.
I don't know how to behave. I haven't told anyone we've gone past the first date, nor did she. Which means a few times now I met her after nearly spending the night together to act like she's an acquaintance.

She told me she feels really strange about telling my friend, but didn't give a reason and I didn't ask.

I'm quite sure my friend isn't aware of anything. She has a big mouth that gets even bigger on booze, she would have slipped it.

What's the proper behavior here? Act with a bit more intimacy, push a bit? Let her tell and act the way I've been acting until and if she does?

I've told one of the guys, but we're all remarkably discreet at this point. We grew too old for taking joy at drama and smart enough not to leak.
