Be careful in the conversation that you do not tell her how she feels. That makes a woman furious! Don't lecture her and try to get her to be reasonable. All those actions point to her needing to be different and makes you look "controlling".
It's more about listening to what she wants. Then it's about what you want. Here's the thing, you want to sound strong and confident in place of being freaked out. You want to sound sure of yourself and not pleading, whiney, etc.
When I was a WAW, the more my H made statements about fighting for our M, or statements like that....it turned me off soooo bad! You don't have to tell her you are standing for the M. If that's what you want....then just do it. I really think the less you say about your feelings....the better.
