I'm (32m) so confused why she (31f) said to me what she said and goes out with some guy to eat at the place we both work at?

I'm so confused why she said it to me. Anyways, I know a girl in her 30s and im in my 30s too and she got a child with a boyfriend last year and now she told me he took the child and she's fighting custody battles, and I thought i had another shot with her (i asked her before for a date and she told me she was busy and couldn't make it to the date, but later learned I was told she already was seeing someone else, well this guy that broke her heart) and she seems to like me even told me she was so always happy to see me and hugged me so tightly couple times through the last two months.

So I asked her for a number and she tells me she can give it to me but she's not dating anyone if ever, cause she got beat up by the same guy she had the child with and who took her kid and that broken me up cause two days after that, I see her with some dude eating where i work ) we do work in the same place but i don't have her working with me as I work weird hours)

I'm just confused why she said that and does something else, and she even kissed me on the cheek with a nice tight hug like four days prior to me asking?
