I'm in love with my wife's best friend for many years now, and it doesn't seem to fade away. What should I do?

Many years ago I meet my (now) wife and her friends for the first time. There was this girl there which captured my attention and I couldn't look away, from a distance I stand, not to look like a creep. Unfortunately at that time she was dating someone (handsome fella) and I didn't have much self confidence or courage to approach her or say anything. Besides he was way more attractive than myself so I just stepped back. As time went by her best friend and I dated and got married. It's been over 11 years since and I still has these deep feelings for that girl. I try my best to avoid being around her and will make excuses to stay home or in the office. We don't talk or see each other much but for some stupid reason she is always on the back of my mind. Even if it's just a picture of her, I feel this longing for her, which is obviously almost impossible because I'm married to her best friend and my wife loves and care for me a lot. I've been searching for answers and solutions to resolve this problem but it's always a temporary fix. I honestly think of her every day and it's really affecting my internal life. The funny thing is that my wife and I never had a child and that girl is still single till today, for a moment it makes me wonder. I understand law of attraction and is a very positive and optimistic person, which messes up my mind into thinking it could happen but then I think of how it would affect both my wife and her friend. There are very close and I'm in a very difficult situation. I have tried to move on in my mind many times but her image never fades, I love and care for my wife but I have this deeper love and passion for her friend which I tried to express to my wife but always fail. To be honest I love her more than my wife, which I insane and unfair. I feel like I'm living someone else life sometimes. The girl does date from time to time but it never develops into anything serious, which is weird because she is beautiful, funny and smart. I need help
