Hello my name is Jessica and I need help.

So I have always loved some good D if you don't know what that is then your to young and I will not explain, moving on. I recently got a new job and there is this woman who works there I will call her Sarah. I think I fell in love at first sight she is stunning short hot pink and black hair and a smile to die for. Now I've always thought girls were cute but not like this. And today as I napped I had a dream about her in this dream she was into me and she kissed me for the first time my heart started racing and I got light headed 😵. To say that I want her is an understatement of the century. I am currently in a relationship with a man and have a two year old daughter. But I want Sarah 😩 so bad. And I don't even know if she likes girls or she just looks like she would lol, how do I find out without coming off as rude or getting my feelings crushed into a pulp?
