my problem is that i am in love with my sister in law. although i had known her even before i met my wife(who i love) 3 years ago something clicked in my mind and i can't get her out of my mind. she appreciates me and before getting married she used to say that she wanted to find someone like me. Even today when we talk she often says that we two match in many things. words like these drive me crazy and i want her even more. what can i do?
