Should I Have An Affair?

I am married 30 years and in my 50's. My wife lost all interest in sex about 15 years ago. Since then I have been living like a monk. But I like sex and want to experience sex but with someone that cares about a relationship, even a secret one. On the other hand, I cannot leave my wife. She is depressed and I doubt that she could survive on her own. While there is no romance in the relationship and she is actually quite abusive, I also feel responsible for my wife but have realized that I have a life as well. Can anybody share similar experiences? How did you deal with it?
