Gr8, in my sitch, after close to 3months of NC I reached out to my wife initially to talk about divorcing. One thing led to another while we were talking and she asked me out to the movies.
I thought that was kinda a weird, so I suggested we just go out for drinks one night.
We did.
We've been "dating" ever since that night.
The friendship is building on its own during this time.
It's almost like when you first meet a girl you like and start dating her. You don't tell her you need to be friends first before you date... You just date, and the friendship grows naturally during that time.
