Why did she forward me a message that she received from another man?

So I met a woman through work, but she works for another company. We've been talking to each other for months, but in the past month or so started to have much more contact with each other, we call or text each other daily, but we are yet to meet.

We flirt, and are vulnerable and supportive of each other when we need it. She comes to me with her problems and I feel like I can go to hers with mine - but its not all problems that we talk about.

I really like this woman, I think about her a lot, but neither of us has made a direct move on the other. I've told her what I think of her, but not how I feel. I've suggested we should meet a couple of times, not with any intentions, but she deflects and indicates that she doesn't think we would work, but we get on really well. She then proceeds to talk romantically to me, asking me about my love history or what my love language is etc, so I'm a bit confused as to what she actually wants.

I know other men would be interested in her, it would be impossible for them not to be. She has told me about men which were interested previously, but didn't work out including ex's. This does make me jealous, but that's my problem, so I just listen to her.

This is the first time she has shown me any messages she received. It was a very flirtatious text from a co-worker and very inappropriate. She told me she's not shown any interest in him, and didn't like the message but won't report him. I know her well enough to know that kind of message wouldn't work for her anyway.

I guess my question is two-fold, what do you think she wants overall, and why did she show me the message?

Your in the friendzone, she just wanted support
She likes you, but wanted to gauge your reaction to see if you like her too
She was showing you she has other options

I bit the bullet and spoke to her. In this instance, she did just want my opinion. She showed it to others too because it was soo inappropriate.
She does like me, but we've amicably established nothing intimate can happen between us due to things in both our lives which cannot be changed.
For any men reading this in a similar situation, my advice now would be to talk to her, but approach the subject respectfully and with calculated timing, and absolutely respect both her and the outcome always
