I too sent a letter like that, also before BD was coming. Sincere apology like that always worked... except that time. My H too didn't even acknowledge it. I slipped it in his work bag before he left for work that day so I thought maybe he didn't read it. I looked the same pocket I put the letter in next morning, it was moved to a different pocket so I know he read it. I honestly think for my case, it only did bad. My sincere letter confused him even more.
If I remember correctly AS said on somebody's thread when he or she wanted to write a letter that he hasn't read a single story here where it did any good. Like everyone said its up to you if you decide to send it not. It's your life but be ready for whatever coming.
If you are gonna send it though, my only concern is that the letter is so long by the end even I felt pressure. It's long and it repeatedly said how you wanted to tell her this but couldn't, what she did hurt you so you couldn't...
And one line particularly struck me "I cannot comprehend you needing space"? I understand "I could not" but present tense? Doesn't it sound like you don't understand why she has to do this?
She has to do this.
Just a thought...
