I'm married but still think of my ex daily for 10 yrs...?

Ten years ago my heart was broken by, what I call, the love of my life. We fell for each other very fast and very hard. And then just like it started, it ended and she moved back to her hometown, I was destroyed. We rarely speak or see each other if we do its at a social event in her city that we always attend and mostly just Hi or a head nod with many looks shared. Around 7 months after the break up I met the girl I eventually married, I love her dearly which leads me to my inner turmoil. I don't go out of my way to think about my ex, it just happens. ALL of the time! Although we were only together 3yrs the relationship had such a profound and powerful effect on me, and that is not an over exaggeration in the slightest. Everything reminds me of her still and I feel like I'm doing some kind of hurtful thing to my wife, although I can't help it. What concerns me is that the constant reminders and memories just make me happy. I love to think about her. She was the greatest time of my life, and the way things are looking it will never change. We haven't talked in 10 years and she is now married, neither of us have kids, but lately I have considered reaching out to her but to see her and talk. Naturally I can't talk to anyone about my little "obsession" about my ex.Is this something that I should seek to see her and get closure? It has been this way for 10 years, and shows no signs of stopping.
