Please Advise: This Beautiful Girl is Ready to Be With Me But She Has A Boyfriend..

So I met this girl at work. She is very attractive. I definitely want to get to know her. My First day I saw her I we both just basically eyed each other the whole daY.

So I started asking about her and she found out. We finally talked yesterday. It was kool we flirted and and flirted. So then she was leaving and said Whea my boo at..referring to me.

 Hugged me and then I ask if she had a man..she said yea. I said are you happy? She said yes but she could be happier. What does this mean? We have been texting all day and night. She said she doesn't trust her man.

Im confused of what I should do.
