Had an affair?

I fell in love with someone who was in a troubled marriage. He left his wife and wants to pursue a life with me. We love each other deeply. Do you have a similar story? If so, please share it with me. I want to spend the rest of my life with this man, even against the odds. Is there any advice you can give two people who have fallen deeply in love, despite the less than perfect circumstances? How do you handle society's disapproval of you?
