Sox, darlin... It's ok to tell him how your feeling about things. Just leave out the whole if you avoid I will be filing. Just do it, if he doesnt talk when you get back and discuss that then file. If he wants more he will tell you after you file if that is truly what you want to do.
If you are only talking divorce to scare him and you dont mean it, then you need to totally rethink how you want him to handle the letter. This is basic babe, you know better.......
