Yes, after all of the emotions on this roller-coaster ride from hell, I think that sadness is the actual winner. We go through rage, indignation, sorrow, sadness, fear, incredulity, anger, devastation, on and on..but the final thing we are left with is sadness.
When my husbads affair started we had been married over 30 years. We are still together but nothing will ever really be the same and that is truly very sad.
So sorry you are dealing with this. Thank God women are strong. We damned well better be.
