Erin, funny, I NEVER considered it from his point of view:)  So I certainly was not of the mindset of protecting or walking on eggshells around him.  I didn't want YOU hurt.  I was afraid that even though you say it's over, you would have been happy with a reply...maybe not the purpose of the letter but just an I want him to finally get it...see what he is losing...& maybe he will apologize, think twice about ending it, hold on to the relationship or be sad for what he is losing...& might be sad without a reply or maybe even worse, he might reply only to be draw you back in for a bit to just kick you to the curb again.  My thoughts were purely about you.
