Now, I have a few questions I'd like to ask her. Does she see changes in me? Does she see these changes as positive? Why does she think things won't be different in our marriage?
Because you're like the thief who only repents after he's been thrown in prison. She has no way of knowing that you won't go back to your previous ways as soon as the pressures of marital life return and the pressures of single life are eliminated. However, I really do think your sich is more hopeful than my 2bx's because at least she seems to be unhappy with your separation and miss you. I have zero desire to ever share a living environment with my 2bx again so the sexual problem is pretty much moot.
