I’ve been very fortunate to find my perfect companion.. we just “celebrated” five years of friendship.  It truly is a friendship now - we chat regularly, sharing details about our lives that would be way out of bounds in any other relationship.  We know we can completely trust each other and are always honest with each other - on any and all subjects.  
It’s convinced me I was right to focus on only 1 lady when I sensed she might be unique.
