I stopped by your thread to read your story. You are having some really good things happen! I need to read your thread often. It has really lifted my spirits.
I noticed your analogy about taking it slow like you do in the beginning of a new relationship. That makes a lot of sense to me. I think you do have something there.
Take things slow and let time take care of everything. I learned to become really patient during all of this mess. One thing is for sure. Time makes everything better. I think enough time has passed that a lot of the hurt is beginning to fade and your wife if beginning to soften.
You know what to do. Keep expectations low, be patient and remain positive. Yes, there was something to the kiss. Don't second guess that.
