Don't know what's going on

So I asked one of my coworkers out for a date the other week. She said she’d think about it, then called me a bit later to say ok. The first thing she says to me when we meet up is that she’s not looking for anything right now, and she doesn’t date coworkers. So I say that’s fine, we could just stay friends. We spent the entire day together, and I didn’t get any signals of her distancing herself from me, nor were there any awkward moments. As we were about to go home, we even took a detour and dinner suggested by her. So I thought, cool, the friendship isn’t over.

The next day she avoids me like the plague. And this goes on for a week, and now she’s slowly talking to me again. I don’t know what’s going on. I don’t know how to act around her now. Why was everything fine during the hanging out after rejection, and then awkward after?

How old are you? how old is she?
Other than that, you DON’T shit where you eat. This is basic.

I have the feeling that she’s transgender. It’s just a gut feeling I have, but I’m rarely wrong.

She doesn’t date coworkers. Doesn’t want tales told at work. Doesn’t want any confusion on this point.

she likes you, against her principles of not dating at work (generally smart but a lot of people do end up marrying people they met at WORK).

but dating at work when it goes sour could result in you leaving, her leaving or the both of you leaving that job.

but she likes you.
