The human mind is such a confusing and interesting thing. I dont think you should feel embarrased but maybe you should think about the repercussions of what this would mean if you tried to form something deeper than a friendship with her. The consequences wont be pretty for you and your family. You sound like you like her but prolly dont understand completely what your feeling. I think its possible she has alot of characteristics in a girl that you like that you havent seen in other girls so your immediately drawn to her. Reexamine yourself and think this through!
