My wife loves someone else. What do I do?

Hi. My wife is in love with someone else, a friend of hers. She has known him for over 2 years now. We have been friends for over 10 years and are married for more than a year, but she has always been in love with him even before our wedding. She got married to me because of family pressure and the fact that she did not want to hurt me and her family by breaking it off. Even though I knew that she was having an affair with someone else, I got married to her hoping that things would change after marriage. But it continued to be the same. Even today, she goes and meets him when she feels like and I know they are still having a physical relationship. She has never even hugged me once after our wedding. It's not that she hides things from me, she tells me everytime she is going to see him and I feel helpless. If I stop her, it only angers her more. She feels stuck in this marriage while being in love with someone else. She has absolutely no feelings for me other than us being good friends. Everytime I try to get close to her, she brushes me off. I don't know if this will ever change and if she will ever love me. What can I do to make her forget him and love me instead and be my wife and not just a roommate? There are times when she has just left in the middle of the night to go spend the night with him. We all live close together and it's going to be hard for us to move away anytime in the near future. I stay patient because I love her, but it's heartbreaking to just imagine her sleeping with someone else. I keep hoping that if I be this way, she will someday realize her mistake and come close to me. Is this marriage ever going to work?
