How can I tell if my female boss is attracted to me?

Ok, so...I have a huge crush on my boss. I have worked for her for 15 months. I have a feeling she is attracted to me also but is not going to jeopardize her job by acting on it. She talks about me quite a bit to coworkers. She tells me I am sweet ALL the time. She stands close to me when she is talking to me and sometimes looks me up and down. She often blushes when she is talking to me. She is pretty much known to not text people from work that are under her, yet she always replies to all of my texts, like literally every day. Even on the wknds. I have never told her about my crush on her but I have made it pretty darn obvious. She has to know!....I bring get her coffee all the time. I bring her bracelets that I have made. I have given her dozens of cards and notes telling her how awesome she is and how much I like her and I always sign my cards and text messages with either a heart or xo. I have received 3 cards from her in the last few months telling me how sweet I am and that I am a good employee. She gives me Starbucks gift cards, no one else that works for her gets them. For Christmas she snuck me a present and card and told me to stay quiet about it. The other day she gave me a gift bag with three pairs of earrings she had made for me. She told me that she has kept all my cards and is making them into a posterboard. I am very attracted to her. I realize that she would not be allowed to have any sort of relationship with me because of the rules, I just want to know if it sounds to anyone else like she is attracted to me. I would be happy just to know she is.
