This is the first time I've ever posted a question on-line, but don't know what else to do.
I guess some background should be first.

I have been married for 16 years and my wife and I divorced about six moths ago.
The rigors of my job and just growing apart. We're still friends.
This is my third divorce.

I'm rusty at the "dating" game, so I think I made a fool of myself.

I'm a Cop, 45, healthy and in good shape. I'm a competitive power lifter, also active in a lot of other sports.
I guess I would say I have average looks. Not bad, but not great.

Background on her:
There is this girl that I have known for about 4 years now.
We have talked socially and as friends for the last four years, worked together (rarely because we don't work in the same department) and even though I have been crazy about her, I never let on because I was married and she has a boyfriend of about six years. She has two daughters (16 & 13), I have a son (21) and a daughter (27). Nether of mine live at home. She has been married twice before.

She's a Cop, 35 and VERY pretty. Has a great personality. The nicest girl I know.
Whenever I'm around her, my heart rate jumps up and stays there, my hands shake and my mouth gets so dry I can hardly talk. I've never had anyone effect me like this before.
I've always tried to hide it from her and I don't think she knows how she makes me feel.

We've spent some time together here and there. Nothing sexual, just drinks or conversation.
We talk almost everyday by phone or email (we did anyway) about everything. She has said that she and her boyfriend are not close and they just kind of "exist". I think she knows how I feel about her even though I've never said anything.

I have been told that she and her boyfriend don't get along very well, but that she doesn't want to leave him because he is the only father her girls know, and he is good to them.

Anyway, she asked me out about a week ago for the first time. Not really a “date”, but just getting together for a couple hours. Because of her situation, I never felt it was right for me to ask her out.
We had a good time. Laughed and had a drink at a local restaurant.
Talked about her kids and mine, work and a ton of other things.
I asked her how it was working out with her and her boyfriend and she again said they were just existing.

At the end of the evening I walked her to her car and we stood outside of it for a few minutes. She said she had a good time, I told her I did too. She asked me for my cell phone number and I typed it into hers for her.
Then we kind of stood there for what felt like minutes, but was probably only a few seconds without saying anything and just looking at each other in the moonlight.
She looked beautiful. I can still see her face.

I guess I then said something stupid like “We'll have to do this again sometime", she said "I'd like that".
Then basically she got in her car and I got in mine and we left.

Late that night, I sent her an email saying I had a great time and would like to see her again.
I think this was a BIG mistake and don't know how to fix it. Too soon I think.

I haven't heard from her by email or phone since then.
Its been over a week.

I don't know what to do.
Wait for her to call/email me or should I call or call/email her?
Should I take the “hint” and leave her alone?

What if she's waiting for me to call her?

I'm worried she's such a nice girl she may not want to hurt my feelings and may not know what to say.

The problem is I “feel” from the things she's said and done over the years, that there is an interest or attraction there. Especially in the last few months.

I would like to talk to her and just ask her if she feels there is "somthing" here, and if not at least I would know and not be in limbo.

What should I do now?

She has your number, now go on with your life and don't get antsy, she has a boyfriend remember. Yes there is interest, but you are not 16. So Be friends and remember boyfriend in picture! And two at home teens. Patients.
