Don't bring up your relationship. In what ways have you changed?
As far as changes go: I'm more diligent about house cleaning and repairs. Before,she'd handle most of that. I'm taking more initiative when it come to the kids activities. I haven't looked at porn. I make eye contact when she or anyone else talks to me. I notice that it has an impact on most people I interact with. I only contact her when it is necessary. I make myself scarce when we are both home. I don't expect her to cook on her days off. Keep in mind, I normally cook.
I'm sure there's more, but this is what i am consciously doing.
