Question about civilian woman

I know how to date and fuck strippers so well that I could do it in my sleep. But I've spent most of my life married, and except for strippers I haven't dated a woman other than my wife for decades. So at this point I have very little instinct for dating and fucking civilian women. Thus the following question. Was this woman hitting on me?

I'm in day long business meetings with a half dozen people. One person there is a mid 50s woman who works for a different company but was working with me today. She was one of those rare over 50 women who is still very attractive. I'd say she's an 8.5 without any age adjustment. And she had a low cut shirt that generously showed off her natural b cups. I tried not to stare, but when you frequent strip clubs it's hard not to stare at a woman's natural breasts on display. She caught me looking a few times I think. Didn't seem to mind although she did hold her shirt a couple of times when she leaned all the way over to avoid a complete view.

So we had maybe a half hour alone together and talked about all kinds of stuff. She mentioned that she's divorced as did I (although of course I have no wedding ring on so my status is obvious). She also briefly mentioned a boyfriend in passing but only once.

So half way through the meeting she gives me her business card. Nothing unusual about that cause it's possible that I may need to contact her regarding follow up work issues. However, before she gives me her card she writes her cell number on it. She says I'm giving you my cell so you can contact me about a certain work issue between us. I said thanks.

Upon reflection there is zero business reason for me to have her cell number. I've dealt with people similarly situated hundreds of times in business. They almost always give me their business card but never a cell number. Most communications are via email, and I can't think of any business reason to need or use her cell. We could easily address the business issue between us with a quick email.

So was this woman coming on to me by giving me her cell number? She knows that I live far away from her so a relationship seems unlikely. But she does know that I'm sometimes in her town for work.

As she left I told her that I would arrange things so that we could work together the next time I'm in her town. She said that would be great. I wanted to say that I'd like to get together with her for a date next time too. But I was worried that I was misreading the situation, and it would turn very awkward. Things are so much easier with strippers. But I would love to fuck this one.

Was she coming on to me by giving me her cell no. If so, what should I text her to set the stage for the next time I'm in town? Or should I just wait until I see her next time. If she's wearing the same or a similar top, I'll know cause she could no doubt tell how much I liked it.
