Things may seem bleak now BF but I assure you things will work out. When my husband asked me for a divorce he totally blind-sided me. I thought our marriage was perfect, we never argued or anything. I never saw it coming and thought it was the end of the world. He just came home on our anniversary and said I don't want to be married anymore. I was devastated, I lost not only my husband but my friend. My biggest fear was that I was going to die alone. I honestly think this was the start of all my psych problems.
But I found out he had been running around with my best "friend" for over 2 years. So in the end, he did me a favor.
You will get over it. It will hurt for a while but your pain does subside.
