Married but feeling lost. What do I do?

I am with my husband for 8 years. We have children together and I married him with the thought that we would be together forever. Before I met my husband, there was a guy and I used to flirt a lot. We lost touch for a few years. This guy ended up later moving to my home town but by then my now husband (then boyfriend) and I were rock solid. Fast forward years later, this guy is married to someone else and I am with my husband. We have kids the same age at the same school. I see him often and he is constantly smiling at me. A mutual friend told me that he has heard him talking about me obsessively as well. He is always going places he knows I will be and it always looking for ways to get my attention. I was kinda blind about it at first but I now see him staring at me and smiling or looking me up and down. At first I just started crushing on him for his looks but my feelings have turned into real feelings. I haven't felt in love with my husband for a few years and I feel stuck. I want to just be happy and live my life the way I imagined it to be. I feel so depressed and I feel like the most horrible wife for having feelings for someone else and stupid because this other guy is too shy to even talk to me. I feel like a fool and a terrible person. I can't control how I feel. I just want to be happy but I'm afraid.
