My friend said she is attracted to me

My friend who is married recently has been opening up to me about her past. She has mentioned before that she has had dreams about me but never went into details. Now last week she told me that she is attracted to me. I'm not sure why she would tell me this, because i'm sure she is happy in her marriage. Now I'm confused and feel a bit uncomfortable when I'm with her. Guess best thing to do is wait and see wbat happens. I really like her as a friend and don't want to risk losing her.
