I'm attracted to my boss

I've been suppressing it for quite some time, but there are days when I can't make eye contact with her. I think she knows, and we both admitted there was some type of vibe, but the overall discussion was vague. I think she could possibly be dating someone that works with us. It's driving me crazy. As an act of expression, I have purchased a gift for her that's personalized. I haven't given it to her yet.
