It is hard to regain lost feelings. I know because I've been there. My husband left me mentally alone many years ago. I tried to leave but circumstances kept me in the marriage. We are closer but not back where we used to be.

It sounds like you are working at it and I hope it does some good. I know people who have rekindled a relationship, so there is hope, especially since she let you have 6 months to work on it. I wish good luck.
