It's all so normal. I've been separated/divorced for over 7 years, and while I have dated, there has not been one man integrated into my everyday life. I am honestly terrified (yet ready) to bring someone into my life. I've had so many years of my own GAL, my own work, by own journey of just surviving to actually living, and living with balance, I'm worried about the challenges and issues, ect. that might bring.
And you are doing this with your wife, while overcoming an A, and while she has her own issues to deal with. So this is going to be a tough, slow, sometimes backwards process. You just got to keep your eyes open, be aware of what makes you uncomfortable or reactive and work from there.
