Update - perhaps I have a new crush! She's a co-worker.

I'm having some mixed feelings and thoughts about her.
She's a very friendly and playful person when interacting with men. However I sense she's the kind of "daddy's girl" kind of person because she's going abroad with her father, so she may be a little oblivious to romance, but she's so cute and we have a great conversation chemistry. I also feel I have some feelings for her, yet I feel she has some insecurity about men, so I'm not sure if going "strong" or "direct" is the right thing to do.

Here's the story:

Yesterday we worked together evening.
She mentioned Valentine's Day and about how we'll all spend valentines day alone, yet how being single is an advantage kind of small talk.
I didn't say anything, other than feeling an impulsive "now's my chance" feeling.
But I talked to her as usual during work and breaks, getting to know her, listening to her, talking greatly as usual. I let her drive me near my home to be with her for company and offered her to show me the pancake restaurant she mentioned today sometime.
I offered tomorrow, but we can't, and she's going abroad for a week this weekend.

I personally don't make such a big deal about Valentine's Day, but I have this exciting feeling of wishing her a happy Valentine's Day and that my offer to go to the restaurant was a date offer or something.

Although the thing is, because of the insecurity I sense and the fact that she reminds me of my last ex who also had a juvenile behavior, I feel that I need to take it slow. It's only because it's Valentine's day, and while I personally don't make a big deal out of it, my heart tells me it's a kind of a "stars-align" day.

What do you say?

From all this writing and overthinking I just told myself "You're overthinking(/feeling), so relax a bit and wait". Still want to hear from you all, though.
Thanks for the support!
