I had the same problem about the porn addiction. My W was very upset and felt worthless and not loved at all. There were other obvious issues, but that was the straw that broke the camels back. I have been clean for over 7 months now, about 3 months before we split. It's hard, but try to put yourself in her shoes, and feel like she felt. That's what it finally took for me, and really wanting to change for my kids and future.
Good luck on the date. And yes keep it super slow. The hardest part may be to try and bring up what you are doing to better yourself, from what I understand in the DR bible, very bad to do and will only make you seem selfish. Try to focus on her and what she is doing. Listen and them listen some more. If she brings it up just be cool and controlled.
And after reading your stich, a lot of similarities. Nursing school, work full time, but added kids and 2 dogs. So I understand the stress, and wanting to feel fulfilled with the porn. It might take a while, but you are hopefully on the path. Good luck again!!
