I hear you. I know if she ended this A we could work on our M. We really have had a lot of fun together, which I know is confusing her. She even said last night "today was fun but what does this mean for tomorrow and the future?" I said "I know that we will have ups and downs, good days and bad days, and then more good than bad. But we cannot even go that direction as long as you have any contact with the OM."
I need to take this one day at a time. Just back off, be pleasant and treat her like a neighbor.
