Wish I knew what to tell you. I often feel like I'm close to that conversation myself.
Now that you've had it, I think you've got to follow it up. You drew the line in the sand. You've got to show her it's for real.
Can you move forward now that you've told her that's what you're going to do?
Dunno about everything else. My H just invited me to go to London with him in December. He wants to take me out to a fancy dinner sometime soon. I said yes to London (I lived there as a student, and will have long days to myself, which I can easily fill!), so that's booked. But dinner...it's hard to muster the energy to go out with him anymore, honestly. I feel mostly dead. He is lavishing lovely words on me, but they're falling flat. Who cares if he loves me if it's not only me? It's not what I signed up for or what I want.
Never have I accepted this in a relationship. I feel as though I am only tolerating it (barely) now because we have children who deserve a singular household. Nevermind the fact that I know that this is not a healthy relationship right now.
