He notified her by email?? That's aweful!!
My cousin has gone through a divorce just recently, it's very very difficult, and yes they feel rejected, sad, angry, humiliated, lonely, i stood by her and worked through this with her. She said, it's like grieving. She cried buckets over this man, and they wanted to work through this divorce "peacefully" but that was impossible for her. She loved him so much, yet he left her for another woman.
