I think you answered many of your own questions in your post. Its about you, if u want to make that effort, then so be it. If and when its time to walk away, only you will know.
The community is gonna support which ever decision you make. I know the feeling of wanting to say you did everything you could to save your marriage.
If you cant get comfortable with the idea of dating, well, then its not time yet. Keep up with the changes.
I'll keep an eye out for updates, or venting. Good luck to you, I hope you find what you seek.
