If you are both friends, then she likely knows that you "like her". Verbalizing it would only make things more awkward. I'll give you a personal example. I am married, there is another married couple that have been close friends to my wife and I for a very long time. To varying degrees and over the years, I have found my friend to be attractive and have had an ongoing.... "crush" on her. I even suspect that the attraction may be mutual. It would be foolish, disrespectful (to my wife, my friend and her husband) for me to say something. Nothing good would or could come of speaking about it. So, I keep it to myself. We (as human beings) can't control who we are attracted to. We CAN control our actions regarding that attraction. And in many instances, we should control those actions and keep our "feelings" to ourselves.
