Here's some samples :

WIFE : Our marriage was a sham.

YOU : I love you and our family, that's all I care about right now.

WIFE : The OM is what makes me happy now.
YOU : All I want is what is best for you and our family, breaking up a home isn't healthy for us or our son. I love both of you so very much.

WIFE : You never made me happy.

YOU : I made a lot of bad choices before. I am working with our church and I am only wanting to be a good person for you and our family now. I can't change the past, but I can keep it from coming back. I am even volunteering at our church now. The priest there is a great influence to be around. Great man, I am proud to know him.

WIFE : I hate you

YOU : I love you and our family, I am sorry you are so sad right now. I am doing everything I can for you and our family. That's the person I want to be.
